Is such a thing possible? I have a search page and the user clicks a link to edit a document and it takes them to another page.
The user then hits the browser's back button i want to take them back to the results that they left off on so they don't have to search again.
EDIT: The search works as the user enters in parameters and it goes out to the database and returns results in a type of search result viewmodel. That viewmodel is parsed out to a table format and shown on the screen. Each row has certain bits of information tied to it like the primary key and other things that the user can see.
Once the user hits edit it uses the primary key to go back to the database to get the remaining data for that row and shows them a form on screen. If the user hits the back button on the browser I want to take them back to the result set that they just viewed without having to redo the search.
The way we have it setup is when the user hits back it goes to the index method that just does a new search page.
You can do this using the HTML5 History API. For instance, when the search returns its result you can use:
history.replaceState(..);
to modify the current browser history entry. It isn't compatible with some older browsers though, so if you have to support those, this may not work properly - or you'll have to find a workaround.
There exists a couple of 3rd party angular modules out there that wraps the history API, but it should work just fine on it's own.
A way I've done this is by using a controller extension method to get the page's search state from session. I'm sure there is a better way to do this in Angular though.

I will try to explain my situation and what I wanted to do. There is not any difficult and rare situation, but I can't find any relative questions or articles in internet.
I have created a web application on ASP.NET MVC 5. Users are not going to enter my application directly. Users will enter let's say to CentralInformationSystem.com. Then they must login to this website one of supported ways. After signing in, they will see a list of applications. There will be applications which has been allowed to use for the signed user. One of this applications will be my application which has developed in Asp.Net MVC.
And the main point is that our applications will not be opened in other tabs or in current tab and so on. Our application will be opened in a big iframe inside the current tab.
And other main point is our applications and CentralInformationSystem.com belong to other domains.
The other question of course is, how then I can now which user has signed in? And the answer is, CentralInformationSystem.com sends encrypted data with the query string to our web site. For example, the URL will look like that:
MyMvcApplication/Home/Index?Token=jkndid758adsai==qwdbqwiudhqwadoqidwqq=wqdiqw
Also keep in mind that they will always sent different tokens.
And after that, I will decrypt token and find to which user it belongs. Also keep in mind that, one Token can be used only once.
1. What type of application is my application?
User will enter very big form. It can actually take almost 3-4 hours. So, I have tried some-type of wizard logic. After entering some portion of datas, I will insert them to the database, get identifier from the database and store it somewhere and take the user to the next level and so on.
2. What I want to achieve?
I want to create such logic that, some identifier variables values must be stored in such place that never must be expired till the user closes browser or signing out. I don't want to increase session timeout to 5-6 hours.
3. What if user opens my application in more than one tab?
Alongside 2 I have also one problem, that user can open my website inside iframe more than one tab. I know that, in Asp.net we can differ session per each tab. But, I don't want to store datas in session, because user can stop filling forms after 20 minutes or 4 hours. Also, I cannot use cookie, because cookies will be same for all tabs.
My other option is, to inject hidden inputs with encrypted value to all views. But, I can't find how to automatically add these datas to each views. Also, it doesn't seem to me as most efficient way.
The other logic is to prevent user to open same application in more than one tab with differen tokens. But, don't how to achieve this also.
Additional:
I have read almost all articles and questions/answers. I know how to make it work. But, I want the best approach. Neither of my approaches are efficient.
Use your own concept of a persistent session that is identified by a hidden input on the page and does not expire, or at least does not expire for a very long time. Have all of your controllers derive from a single base controller and use the OnActionExecuted to add the session "key" to the ViewBag when the result is a ViewResult (you won't need it for partial views or JSON, etc). Every page can then access the ViewBag and create the hidden input - probably you want to use a partial view for this and simply include the partial on every page. Store the data associated with this session in the database.
I'm trying to help save time at work with for a lot of tedious copy/paste tasks we have.
So, we have a propitiatory CRM (with proper HTML ID's, etc for accessing elements) and I'd like to copy those vales from the CRM to textboxes on other web pages (outside of the CRM, so sites like Twitter, Facebook, Google, etc)
I'm aware browsers limit this for security and I'm open to anything, it can be a C#/C++ application, Adobe AIR, etc. We only use Firefox at work so even an extension would work. (We do have GreaseMonkey installed so if that's usable too, sweet).
So, any ideas on how to copy values from one web page to another? Ideally, I'm looking to click a button and have it auto-populate fields. If that button has to launch the web pages that need to be copied over to, that's fine.
Example: Copy customers Username from our CRM, paste it in Facebook's Username field when creating a new account.
UPDATE: To answer a user below, the HTML elements on each domain have specific HTML ID's. The data won't need to be manipulated or cleaned up, just a simple copy from ourCRM.com to facebook.com / twitter.com
Ruby Mechanize is a good bet for scraping the data. Then you can store it and post it however you please.
First, I'd suggest that you more clearly define exactly what it is you're looking to do. I read this as you're trying to take some unstructured data from Point A and copy it to Point B. Do the names of these fields remain constant every time you do the operation? Do you need to simply pull any textbox elements from the page and copy them all over? Do some sort of filtering of this data before writing it over?
Once you've got a clear idea of the requirements, if you go the C# route, I'd use something like SimpleBrowser. Judging by the example on their Github page, you could give it the URL of the page you're looking to copy, then name each of the fields you're looking to obtain the value of, perhaps store these in an IDictionary, then open a new URL and copy those values back into the page (and submit the form).
Alternatively, if you don't know the names of the fields, perhaps there's a provided function in that or a similar project that will allow you to simply enumerate all the text fields on the page and retrieve the values for all of them. Then you'd simply apply some logic of your own to filter those options down to whatever is on the destination form.
SO we thought of an easier way to do this (in case anyone else runs into this issue).
1) From our CRM, we added a "Sign up for Facebook" button
2) The button opens a new window with GET variables in the URL
3) Use a greasemonkey script to read those GET variables and fill in textbox values
4) SUCCESS!
Simple, took about 10 minutes to get working. Thanks for you suggestions.
I am working on an ASP.NET/MVC4 app and I fetch data continuously and my problem is related to caching.
The problem is that when I click on a particular link in my application it works fine, but sometimes it automatically redirects to the INDEX page that is the default page.
I surfed around about this problem and found that it's a problem in Mozilla that it maintains caching of every link. But sometimes some weird things happen and it automatically redirects a particular link to the INDEX page (301 Permanently REMOVED) and also stores it in the cache such that now every time I click on that link it always redirects me to the INDEX page that's been cached.
So now I have to clear the cache in my browser every time I face this problem.
How can I make it not automatically redirect to the cached INDEX page?
You should really expand on what exactly is happening at that particular link you mention because well it should not 301 redirect unless your telling it to.
Also you say I fetch data continuously. What does this mean to us? Why is this important to know? Explain if this changes the link or the data? Are you 404ing the older data or something? That could possibly explain why you 301 back to your index.
Now with the limited information we have been given by you... if you want to prevent firefox from caching your urls/redirects simply make your url have a querystring that updates which each request. Like using a timestamp.
For example: http://example.com/return-data.asp?timestamp=1350668920
Then each time you continuously fetch data update the page's link accordingly
For example: http://example.com/return-data.asp?timestamp=1350669084
as i am developing a web application in asp.net, There is 4 text boxes to provide user deatils and a button to save the information in DB. When User click the button to Insert the user deatil, it is saved in DB perfectly, but the problem is when the user Refreshes the page, that data is again re inserted / resubmitted, i want to make sure that duplicate submission should be avoided .
Please any suggestion, code samples, to avoid this situation are welcome ( in c#)
Use the Post-Redirect-Get (also known as Redirect after post) pattern. It simply consists in redirecting after a successful post, so that the user refresh results in an idempotent GET to be done rather than a POST. It has the additional advantage that the browser "forgets" about the POST in its history, which means the back button won't submit either.
Put a field in page call it status for example, after submitting first time it's populated with SUCCESS. If it is the do not save again.
Not the ultimate solution for sure.
We have a sitecore website and we need to know the item from which the link that brought you to page X.
Example:
You're on page A and click a link provided by item X that will lead you to page B.
On page B we need to be able to get that item X referred you, and thus access the item and it's properties.
It could go through session, Sitecore context, I don't know what and we don't even need the entire item itself, just the ID would do.
Anyone know how to accomplish this?
From the discussion in the comments you have a web-architecture problem that isn't really Sitecore specific.
You have a back end which consumes several data items to produce some HTML which is sent to the client. Each of those data items may produce links in the HTML. They may produce identical links. Only one of the items is considered the source of the HTML page.
You wan't to know which of those items produced the link. Your only option is to find a way of identifying the links produced. To do this you will have to add some form of tagging information to the URL produced(such as a querystring) that can be interpretted when the request for the URL is processed. The items themselves don't exist in the client.
The problem would be exactly the same if your links were produced by a database query. If you wanted to know which record produced the link you'd have to add an identifier to the link.
You could probably devise a system that would allow you to identify item most of the time (i.e. when the link clicked on was unique to that page), but it would involve either caching lots of data in a session (list of links produced and the items that produced them) or recreating the request for the referring URL. Either sounds like a lot of hassle for a non-perfect solution that could feasibly slow your server down a fair amount.
James is correct... your original parameters are basically impossible to satisfy.
With some hacking and replacing of the standard Sitecore providers though, you could track these. But it would be far easier to use a querystring ID of some sort.
On our system, we have 3rd party advertising links... they have client javascript which actually submits the request to a local page and then gets redirected to the target URL. So when you hover over the link, the status bar shows you "http://whatever.com"... it appears the link is going to whatever.com, but you are actually going to http://ourserver/redirect.aspx first so we can track that link, and then getting a Response.Redirect().
You could do something similar by providing your own LinkManager and including the generating item ID in the tracking URL, then redirecting to the actual page/item the user wants.
However... this seems rather convoluted and error-prone, and I would not recommend it.
