Other webs can't do "fopen" on my web

My server restricts the HTTP Requests, how can I allow them?

[homeini]

Hello,

Some webs, like 'meneame' or 'digg', do 'fopen' to read a web before the submition of a post. But they can't open my web because my server doesn't allow those HTTP requests.

¿How can I allow them?

eg.
When a web do 'fopen' to my web they get the next error:
failed to open stream: http request failed

Are you on your own server or is it shared ?

It's my own server, but my problem isn't that I can't read other pages. My problem is that others can't read mine.

Look through your iis logs and find these requests, then try running similiar requests from your workstation machine.

Also, you might have somewhere in your configuration some code that blocks based on user agent, maybe an isapi filter or some firewall setting.

Hope this leads you in the right direction

That makes it easier - you should check your configuration doesn't ban certain user-agents. You may find you're banning whatever user-agent Digg's crawler is.

Many standard web server installs block wget, php etc.
