IIS7向URL添加乱码，导致404 CSS文件

Question

I have a C# web application that runs fine when hosted by VisualStudio.

When I host it on IIS, the link to my CSS stylesheet returns a 404 error.

Basically:

http://hostname/Sitename/default.aspx

becomes

http://hostname/Sitename/(S(ubd3fhzfs04ebb1qzfsjlsse))/default.aspx

I dont know what might've changed, but this started happening after a publish a couple of weeks ago.

I have tried deleting the site folder and re-publishing.

I have 2 other applicatins hosted that are also published via VS, and their URLS are normal ie

http://hostname/Sitename/default.aspx

From what I can tell, the web.configs and IIS setups are the same for all sites.

Answer 1

That URL contains a session cookie ID, it is caused by a cookieless session (either cookies are disabled and automatic detection kicks in, or you explicitly set up cookieless sessions, or it is caused by a device-specific ASP.NET configuration). It can simply be fixed by changing session settings. However, I would also fix my static file references to be relative instead of absolute, so they wouldn't cause 404 errors in different setups. Cookieless URL's are handled transparently by ASP.NET, so they don't cause 404 errors on their own, only if you have hard-coded absolute URL's, which is bad practice anyway.
