[Mono-list] Newbie Question: Web app life cycle events

Mon Oct 27 06:12:21 EDT 2008

One possible cause to keep in mind is if Mono is handling all requests
for the app them begin request etc will be called also for css files
and images and javscript, not just .aspx
This is similar to running in the Visual Studio web server. Running in
IIS on windows, requests for css files and images will be handled by
IIS and not by .NET.
It is possible to configure things so that apache handles requests for
css and images, but using xsp2 directly its going to handle all files.
You may be able to find out what the request is for in those events
with HttpContext.Current.Request.RawUrl

Hope it helps,

Joe
