Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator

I have installed apache HTTP server and after when i browse to 开发者_Python百科localhost i am getting this error. Apache server is started. Port is configured to 80 and seems to be no one use it. I can't figure out what is the problem. Can someone? Thanks.

The problem is that you're routing your localhost traffic through your upstream gateway proxy. The upstream gateway proxy refuses to send the traffic back, either because "localhost" has a different meaning to it, or because it's trying to prevent a security threat called "proxy bounceback." What URL are you using to access your site? Put that URL's hostname in your proxy exemption list.

Open the ISA server2006 and create a role and allow networks internal to allow internal and external .And restart the isa services .It will work fine

I tried this and it is working fine.
