HTTP 200 on Styles.css (camel case) but HTTP 401 on styles.css (small cap)

Question

Hello all,

this is a weird one. I have a site deployed on a web server. (Win 2003, IIS 6)

For some reason, I can do an HTTP GET on a file if I specify it with "camel casing".. i.e. Styles.css, but I cannot get the same file using "small cap" i.e. styles.css

In the later case I get a 401.3 exception.

I know that 401.3 is a security issue but I'm confused because as far as I know ACL has nothing to do with case sensitivity.

What is even more weird is that I have (in the same folder) other files that I cannot GET (small cap or camel cap) and they have the exact same security settings.

Any ideas on what the issue could be?

Regards, Alex

Answer 1

Can you check your web log or possibly use Process Monitor to see what happens when that file is requested?

Answer 2

The problem was related to a proxy server in front of my server. This box caches the files so it was not really hitting the IIS server all the time.

Thanks Micky for your help.
