how can fix localhost url in ASP.net

every time when I run my web app in visual studio 2017 this
"(S(zwvqridsdqfqioztfkngivah))" alway come with
URL how to fix it..?
example-http://localhost:64537/(S(zwvqridsdqfqioztfkngivah))/About

The string you are looking at is the session ID.
asp.net can do cookieless sessions by putting the session ID in the URL.
You can turn it off by setting sessionState to <sessionState cookieless="false" /> in your web.config
(keep in mind this will change the behavior back to putting the session ID in a cookie on the browser, but also that cookieless sessions are an easy attack vector, so you should probably do this anyway.)

The (S...) part is the session state identifier. I think you have enabled cookieless sessions in ASP.NET.
In order to switch to cookie-based sessions, change your web.config to this:
<sessionState
mode="InProc"
cookieless="UseCookies"
/>

How to solve session issue on Content Delivery (CD) server using Sitecore 6.6?

In a project (build with Sitecore version 6.6 and ASP.net Webforms) I experience a strange session loss issue on Content Delivery (CD) server. I googled on this subject using the keywords ASP.net and session loss. I found a lot of interesting stuff, but not the solution.
In the meanwhile, I figured out that it is nearly impossible that the cause of the issue is an Application Pool recycle or the auto-bot detect function inside Sitecore.
The way we write data to the session.
System.Web.HttpContext.Current.Session["name"] = "data here";
The way we read data from a session.
string data = (string)System.Web.HttpContext.Current.Session["name"];
SessionState configuration
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;user id=sa;password=" cookieless="false" timeout="20" />
The Sitecore configuration is the default. The session loss is at random times within 5 minutes. Does anyone know a solution?

One possible reason is following setting.
<authentication mode="None">
<forms name=".ASPXAUTH" cookieless="UseCookies" timeout="180" />
</authentication>
Also look at session setting in IIS, probably there is something incorrectly setup.
I would suggest that you try setting up a session state server and see if the problem still persists.
Additionally, it is worth to ask, are you using one or multiple CD servers.

trying to put a timeOut in asp.net

I have a ASP.Net web application in witch i want to put a timeOut (for user that dosen't do anything for too much time). My test use a 3 secondes timeOut. In the web.config :
<sessionState mode="StateServer" stateNetworkTimeout="3"></sessionState>
I get the following error as soon as i run my app:
Cannot request session state in session state server.
I can't find anything relevante for this case...
i tried to put InProc in Mode="" but it dosen't timeout anything.

Looking at this, you're trying to use a State Server and set the idle time between the web server and the state server. To properly configure the web server to use a state server, you must also configure the state server. Go to your state server and run:
systemroot\Microsoft.NET\Framework\versionNumber\aspnet_state.exe
This will install the asp.net state service. Then in the sessionState element in your web config you will need to set the stateConnectionString attibute as well.
<configuration>
<system.web>
<sessionState mode="StateServer"
stateConnectionString="tcpip=SampleStateServer:42424"
cookieless="false"
timeout="20"
stateNetworkTimeout="3"/>
</system.web>
</configuration>
You now have two "timeouts" here. The "timeout" attribute is how long the user can keep a connection to the webserver. The stateNetworkTimeout is how long the webserver to stateserver connection can be idle. The default is 10 seconds.
Hope this helps.

/ip

<sessionState mode="InProc" timeout="1" cookieless="false" ></sessionState>
I mistaken secondes for minutes, the Timeout value is about minutes. So i waited 1 minute for my test...

asp.net session timeout on lost connection

I have an intranet page which needs to not time out (indefinitely) and I'm using JS to keep it alive that way.
But I am having one issue that happens when the user loses the connection (happens frequently due to to going in and out of wifi range) the session times out then.
How can I keep the session up/refresh it if that happens?

How about increase the session time out on web.config ?
<configuration>
<system.web>
<sessionState timeout="120"></sessionState>
</system.web>
</configuration>
http://msdn.microsoft.com/en-us/library/system.web.sessionstate.httpsessionstate.timeout.aspx
Other possible way is to make your database, connected with the user cookie, and use your "custom session" data that are totally connected with your users.

Try using in web config if you are using Form Authentication
<system.web>
<authentication mode="Forms">
<forms timeout="120"/>
</authentication>
<sessionState timeout="120" />
</system.web>

first Sets the session timeout on the server is for all session
Rather than a single Session
out wifi range is the entire network are broken
so not keep alive
You have to use cookie
use cookie keep alive

Session Cookie, auto logout

I am using ASP.NET 4.0 for a site I am making. It has a login that leads to some backend sites. That all works fine...
BUT...
There seems to be a logout thing in the Session cookie. Whenever I login and leave it for a few minutes it logs me out when I load the page.
Does anybody know what I can do to change this... or remove it??

you need to set your session timeout on your web.config:
<configuration>
<system.web>
<sessionState timeout="10"></sessionState>
</system.web>
</configuration>

Default value for session timeout is 20 minutes. You can change it in your webconfig as per your need.
