I am working on an asp.NET 4.0 Web Application, using C#. I would like to redirect the user to the homepage of his browser. Is this possible?
This will be done because internally we are using an intranet, and we would like to make it redirect to that intranet without having to hard code it and since the homepage is by default the url of the intranet, it would be better if we could use the homepage instead of hardcoding it.
EDIT:
We are using IE here, and will not change most probably as that is the standard. So as long as it works with all IE Versions, it's fine.
Use Javascript to return to the user's home page,
e.g.
function goHome(){
if (window.home) {
window.home();
} else {
window.location = "about:home";
}
}
and then call the JS goHome() function somewhere on the page (or even on a hyperlink).
As stated above, use the about:home uri.
Another solution would be to store the intranet url in the web.config and use this value. Then if it ever changes you will only need to change it in one place.
As far as i know it is not possible (been researched alot). But if all homepages are the same why not simply use META REFRESH?
EDIT
Try linking to this: About:home
Go home!
worked for me in IE9
EDIT 2:
Sending user to their browser's Home Page using Javascript
This will get you started for firefox and safari
EDIT 3:
Response.Redirect("about:home", false);
You cannot redirect server side to a users homepage.
SERVER <> USER (server is not the user)
Therefore the server cannot know what the user's homepage is.
So if you you use some sort of javascript redirect, then you sort of can redirect to home, but its a little glitchy.
All in all there is no cross-browser way to redirect to a user's homepage.
You Can't!
You can't retrieve the user home page because of Security and Privacy issues, and there is no Cross-browser work around.
What you can?
You can redirect to any page, so you can simply redirect to your intranet home page.
its also more future proof so that if your intranet homepage changes you just have change to redirect to the new address instead of changing every single machines home page.

I am making a simple website in c#, I have a login system and I want to redirect a user to a new home page once they are logged in, how do I do this?
Also how do I redirect someone to a new page at the click of a button? e.g click btnMath redirects user to MathPage.aspx
Response.Redirect("url");
You can do the above
there are many method available to do so. One of those is response.redirect
Response.Redirect("MathPage.aspx")
Remember to mention path correctly inside response.redirect.

I'm fairly new to web forms development, playing around with a project created using the ASP.NET Web Application template in VS 2010. After the user successfully logs in, I want the user redirected to a page I created. How do I modify my project to redirect the user after login? Any samples / tutorials / etc are greatly appreciated.
Thanks!
To simply redirect to a new page when your user has logged in, use the DestinationPageUrl property of your login control... assuming you're using the Login control that is.
If you need to do anything more advanced you can use the OnLoggedIn event handler for your Login control to perform a redirect manually, or add any code for event logging and such.
If you've rolled your own login control, and are just using things like text boxes and button controls, then in your Button_Click event, you can just use Response.Redirect("DestinationHere"); to take your users to a new page.
After you checked for login:
Response.Redirect("url");
I assume you're using ASP.NET Login control. There's a DestinationPageUrl property of that control that handles exactly that. If login was successfull user is redirected to URL provided in that property.
<asp:Login ID="Login1" runat="server" DestinationPageUrl="~/Admin/Default.aspx">
</asp:Login>
Go to Properties and Set DestinationPageUrl.
Server.Transfer( *url*) ?
(method on HttpServerUtility)
I know next to nothing about ASP.NET, but from my Java web developer daze, redirect is bad because it involves another network round trip to the browser and back when you really just want to continue processing in another page.
And Response.Redirect() really does issue a 302 response code ("try this other url instead") back to the browser. yuck. XP
Server.Transfer() looks like the java version of Response.Forward()
For Sharepoint farm solution development
Page.Response.Redirect("url");
The issue with Response.Redirect() is the 302. In some browsers (eg Chrome) this causes the new session cookie to be immediately invalidated.
In other words, using that method to redirect causes the user to no longer be logged in, so you did not accomplish your purpose!.
Let's say I have a website www.mysite.com and I want it to be a multilingual site. Following are the things I wanna achieve :-
1. When a user visits my website, I want to fetch the user's country's ISO code. Let's say the ISO is "FR".
Now I want the user to be redirected to www.mysite.fr
In case the ISO address can't be fetched, the user will be redirected to www.mysite.com
Now I have used the dll from this site http://ipaddressextensions.codeplex.com/ and used their method which is something like
iso3066code(). BUT I am not able to fetch ISO code based on a user's IP address. What is the best method to fetch the ISO code anyway??
2. I have a differenet master page for different countries. Like for France there is France.master, for Germany there is Germany.master, etc.
What I want is that firstly the ISO Code of the user should be fetched, then the user should be redirected to the site corresponding to the ISO
AND want the corresponding master to load.
Here's a scenario:-
A user from France opens my website by typing "www.mysite.com". Now I want to show the user my site's contents in French so I want him to be redirected to
"www.mysite.fr" AND want the France.master to load for all the pages. What I am doing is check the "Top level domain name" entered by user which is "com" in this case, then I fetch the ISO code
then if ISO exists, user is redirected to "www.mysite.fr"
IN CASE, ISO cant be fetched , "www.mysite.com" will only be opened for the user.
3. How do I redirect the user?? Response.Redirect("http://www.mysite.fr") is failing and giving errors like :-
"Page is not redirecting properly" I tried changing it to Response.Redirect("http://www.mysite.fr", false)
and Response.Redirect("http://www.mysite.fr", true). This didn't work.
4. www.mysite.com and www.mysite.fr aren't two different websites.Just that when is it www.mysite.com, English content will be shown on the website.
When it is "www.mysite.fr", French content can be seen inside the website.
What I did was :-
In the Global.asax file :-
I tried fetching ISO code using that dll above from the site ipaddressextensions. Then I created this Application("UserISO") variable in Global.asax file.((Is this a good approach?))
I needed to make it because I wanted to use this global variable within my Global file itself..In some user defined method.
Then I am setting master page name in a cookie and using this cookie to change master page dynamically for every content page in the Page_PreInit() event.
and lastly I am redirecting the user with " Response.Redirect("http://www.mysite.fr", false)". This response.redirect doesnt work!
Now, AM I on the right path?? I am super confused over how to actually make it work! :(
How do multilingual site redirect their users? Where can I learn about all this ? I have tried and tried and tried but this just won't work!
Lastly, there are not really any domain names set for the site as of now. Running it using the IP address set in the IIS.
So how do I test my site. How do I really go about it. Am I following the correct approach at all??
Please direct me to the right path. ANY help will be greatly appreciated. Thanks!
Belgium has 3 official languages, you can't find my language by just looking at the ip address or the domain.
The best way to find the language of a visitor is to check the language of his browser. You can find it in Request.Userlanguages.
Don't do this. It's really frustrating when you try to assume what language the user speaks. You're bound to get it wrong for someone eventually. Put some small flag icons or the language name choices on your main page in a highly visible place, and let your visitors chose what site/language they want to browse in.
Facebook's main sign in page is a great example of this.
Edit: The best you could probably do is to use the HTTP1.1 Header Accept-Language as a hint, but even then I think you should push back on this requirement of your project.
You get redirect error because the .fr site is probably the same site as .com, but session cookies are only valid for a certain domain which means that Session_OnStart() is invoked on the redirect as well. One way to circumvent this is to override the redirect/ip-lookup somehow, maybe send in a querystring or a specific landing page that you can identify:
www.site.fr/?overrideredirect=true
www.site.fr/redirected.aspx -> which then redirects back to / after Session_OnStart
In order to choose the right master page, you could probably identify which host that was requested and from that override master page in your global.asax, perhaps in the BeginRequest event.
I wanted to know if there is a solution using IIS6 for an application to get rid of the default.aspx text in the url. so for example if a user hits:
www.website.com/default.aspx
the browser only shows:
www.website.com/
No matter what.
It's just for SEO.
I already use UrlRewriting.NET for some rewrites in my app but for I'm not that clever to create a rule for that.
Any help is much appreciate.
Thanks.

I think ScottGu already has the topic of rewriting in ASP.NET covered: http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx.
He covers things such as:
Rewriting using UrlRewriter.net, ISAPI Rewrite
ASP.NET Tricks, posting back (hitting the friendly version of the url)
With your problem I think you need to use a combination of, never linking to 'default.aspx' ie. ONLY link to '/'. Then use Scott's Form Postback browser file to ensure postbacks always hit that same friendly version of the url.
Redirecting 'default.aspx' to '/', which then gets served by 'default.aspx' sounds like a recipe for disaster to me. Just fix your links to ensure you never end up on 'default.aspx' explicitly.
I think the simplest way to change the search results index (assuming it knows about HTTP 301) is to write a little function in your default.aspx's Page_Load that redirects the browser using a 301 Moved Permanently (or 302 Moved Temporarily).
void Page_Load(...) {
if(Request.Path.EndsWith("default.aspx", true/*case-insensitive*/, null)) {
Response.StatusCode = 301;
Response.StatusDescription = "Moved Permanently";
Response.Headers.Add("Location", "/");
HttpContext.Current.ApplicationInstance.CompleteRequest(); // end the request
}
// do normal stuff here
}
If you have something to do URL rewriting, then all you need to do its ensure that your links point to the correct URL.
If you don't fix your links, its up to the browser to decide if it wants to display the actual link it requested.
If you would really like to do a dodgy job, you can use some javascript to make the address bar of the browser display whatever you like, even if its invalid.
If default.aspx is set as the default document to serve in IIS, and all your internal site links contain URL's without the default.aspx then I think that should do the trick.
Although the user can still type in default.aspx, search engine spiders should just pick up the friendlier URL's from your link href attributes.
The way I would do it is to use Application_BeginRequest in public class Global : System.Web.HttpApplication and check the HttpContext.Current.Request.URL for default.aspx, and then use HttpContext.Current.Response.Redirect from there if you find it.
The downside is having a redirect is not always so great and this isn't going to work if you are posting data to that default.aspx page. But you can't simply trick the browser into showing a different url, though you can tell ASP.NET to serve whatever page you want for any request.
In an aspx C#.NET page (I am running framework v3.5), I need to know where the user came from since they cannot view pages without logging in. If I have page A (the page the user wants to view) redirect to page B (the login page), the Request.UrlReferrer object is null.
Background: If a user isn't logged in, I redirect to the Login page (B in this scenario). After login, I would like to return them to the page they were requesting before they were forced to log in.
UPDATE:
A nice quick solution seems to be:
//if user not logged in
Response.Redirect("..MyLoginPage.aspx?returnUrl=" + Request.ServerVariables["SCRIPT_NAME"]);
Then, just look at QueryString on login page you forced them to and put the user where they were after successful login.
UrlReferrer is based off the HTTP_REFERER header that a browser should send. But, as with all things left up to the client, it's variable.
I know some "security" suites (like Norton's Internet Security) will strip that header, in the belief that it aids tracking user behavior. Also, I'm sure there's some Firefox extensions to do the same thing.
Bottom line is that you shouldn't trust it. Just append the url to the GET string and redirect based off that.
UPDATE: As mentioned in the comments, it is probably a good idea to restrict the redirect from the GET parameter to only work for domain-less relative links, refuse directory patterns (../), etc. So still sanity check the redirect; if you follow the standard "don't use any user-supplied input blindly" rule you should be safe.
If you use the standard Membership provider, and set the Authorization for the directory/page, the code will automatically set a query parameter of ReturnUrl and redirect after a successfull login.If you don't want to use the Membership provider pattern, I would suggest manually doing the query string parameter thing as well. HTTP referrers are not very reliable.
The problem could be related on how you redirect the user to some other page. Anyways, the referer url is nothing you should take as absolute rule - a client can fake it easily.
What you're looking for is best done with a query string variable (e.g. returnURL or originURL). Referrer is best used for data mining operations as it's very unreliable.
See the way ASP.Net does redirection with logins for an example.
