pass data (string) to aspx page - not in url

[Guest]

Hi;

I have a IHttpHandler that is generating a page. If it throws an exception I
want to put up a nice page that is based on my master page so it looks good.

How can I redirect from my IHttpHandler to my handle_error.aspx page passing
it the exception in the request, not in the url. I would prefer to pass the
filename, line number and Exception.Message string but I can live with just
the Message.

How best to do this?

Here's another nice, simple way to pass values from one page to another:
(VB.NET code)

'Add data to the context object before transferring
Context.Items("myParameter") = x
Server.Transfer("handle_error.aspx ")

Then, in handle_error.aspx.aspx:

'Grab data from the context property
Dim x as Integer = CType(Context.Items("myParameter"),Integer)

Of course there are a number of ways to pass values from one page to another
besides the querystring there are cookies, session, context, saving to a
temporary table in the database between each page, etc.
You'll have to decide which technique is best for your application.
