PageHandlerFactory does not have a public constructor and it's killing me.

In IIS config, I have redirected all requests (extension = *) to the .net
framework. I have an HttpHandler set to handle all such requests. Now I
want that handler to do some thinking, then assign the processing to an
.aspx page.

I know how to assign the processing to a code-only page (just call
ProcessRequest from the IHttpHandler interface). However, since
PageHandlerFactory isn't creatable I don't know how to transfer processing
to .aspx files.

Can anyone help me out?

Thanks,

Stuart,

You could possibly inherit from the PageHandlerFactory class
and do the customisation that way, but the information you
have provided doesn't seem to make the solution clear.

Optimally you could implement this in a class that implements
the IHttpModule interface, you could then attach event handlers
from the HttpContext within the Init(...) method.

Can you give us a non-technical run down of what you do then
a better solution might present it self.

Mitch,

Thanks for your response. The solution that I've just found (while trying
to write to you to clarify my problem) is to implement an
IHttpHandlerFactory that alters the path parameter that it is given prior to
invoking a PageParser.GetCompiledPageInstance method.

public IHttpHandler GetHandler(HttpContext context, string requestType,
string url, string pathTranslated)
{
    context.Trace.IsEnabled = true;
    return PageParser.GetCompiledPageInstance("the url and requestType don't
seem to matter to the PageParser... see trace for proof",
@"c:\inetpub\wwwroot\testsite\default.aspx", context);
}

Mitch, thanks you for prodding me to be more specific... it helped. If
anyone knows that the url and requestType are valued by the PageParser and
the resulting Page, please let me know.

Thanks,
Stuart

P.S. I've seen people bumming around for ways to directly incorporate aspx
and ascx files from other web apps / servers... I wonder if the PageParser
would allow this?

Stuart,

I think the URL parameter on the GetHandler method is
just for reference. I can't think of a reason why it is
useful, because the RawUrl property provides that information
in the HttpRequest property of the HttpContext. Unless ofcourse
the string provided in the call primes that actual value.

Perhaps someone from Microsoft might be able to explain that
one. Scott, Susan?
