I developed a httpmodule that inherits from IHttpModule to use "Session_Start" event, add the output dll to GAC and adds the "add" tag into web.config in "modules" section. All things seem to be ok but when I go to my website. I got this message "404 NOT FOUND" but I can go to "View All Site Content" in my site.

Why this happening?

what does your module do ? – Steve B Jul 20 '11 at 11:56
it's gonna use some events like "Session_Start" or "Session_End" – Jalali Shakib Jul 20 '11 at 12:02
