c# : asp.net : problem wit session and server.transfer

[vishalgupta]

i have

void Application_Error(object sender, EventArgs e)
{
Server.Transfer("default.aspx");
}
in global.asax

now when i use any state bags like Session["sno"] = "new";
whenever the user clicks on link to a page that does not exist on the server, Application_Error() executes but Server.Transfer does not and it shows that the page cannot be found and does not transfer to default.aspx.
why is Server.Transfer not getting executed ??

[kunal pawar]

rather than to use server.transfer

add following code in ur web.config

<customErrors defaultRedirect="default.aspx" mode="On">
</customErrors>

[vishalgupta]

this wont work as i have to display the url that the user has clicked
i.e http://localhost:1126/N/default5.aspx

but customerror displays
http://localhost:1126/N/default.aspx.../default5.aspx
in the address bar

is there some other way to do this??

I think that you may benefit from this overview:
How to create custom error reporting pages in ASP.NET by using Visual C# .NET

I'm not sure what you are hoping to achieve, an application error is unlikely to display the default page (hence the need for error handling).

i am sry but the above link doesnt slove my problem

i have a link on my page which points to default5.aspx
but as default5.aspx does not exist on the server the Application_Error is invoked :
void Application_Error(object sender, EventArgs e)
{
Server.Transfer("default.aspx");
}
which tansfers the user to default.aspx but shows default5.aspx in the address bar.
now if i use state bags like Session["sno"] = "new"; itshows the error that default.aspx is not found on the server.

if use customerrors in web.config then it does redirect to default.aspx but shows some asp error url in the address bar.
but i want to display default5.aspx in the address bar
but how??

When you use Server.Transfer the requested URL is displayed in the browser.
The reason is because the Server changes what ASPX page to display....

For example:
The user requests the requestedAspxPage.aspx :
The requestedAspxPage.aspx doesn't exist, so you call Server.Transfer(anotherAspxPage.aspx)
The Server uses anotherAspxPage.aspx instead of the requestedAspxPage.aspx.

Since the server handles this, the URL in the web browser is not changed.

Now, if you use Response.Redirect(anotherAspxPage.aspx), the server returns an HTML code indicating to the browser that it should request anotherAspxPage. The URL is changed and the browser requests the "anotherAspxPage" instead of the requestedAspxPage.

I would use Response.Redirect for "Page Not Found" (404) errors...because if the url still points to a page that doesn't exist, the next time the user does a postback another error will occur again.

You can Rewrite the URL if you want...
See URL rewriting in ASP.NET for more information on the topic.
