Dynamic "Response / HTML Content" without an ASPX -Endpoint

[Patrick]

hi

several general webpages (more or less static, e.g. errorpage,
timeoutpage etc.) i need in all kind of asp.net-applications.

instead of copy this pages (the *.aspx or *.html) into every
project explicit, i'd like to consolidate them into a single dll,
which i can reference and use in every asp.net-application.
- that's the idea....

now, i'm searching for ideas howto realize this...

i could imagine the following solution:

implement "front-controller" (httpmodule or httphandler) which
intercept the incoming requests. predefined adresses (e.g. error.aspx)
are filtered and not further forwarded. instead, the appropriate
response-stream will be send to the client. as long as the
response-content is static, it could be included in the assembly
(=front controller) via an embedded resource.

what do you think about? alternatives? ideas? solutions?

second question:

is it possible to create a page (system.web.ui.page) on the fly
(page.controls.add etc.) an send this page back to the client
pseudo code --> response.write(myPage.ToHTMLString());

this could be usefull e.g. in application_error event in global.asax,
if you won't redirect to a separate aspx-file.

thanks
