Hi,

I am looking for some resources or information on how reverse proxies can help defend web servers against attacks. I have googled and found a few articles on SANS and a couple of technet articles however I am more interested in specific attacks that may be stopped. Here are a few articles that I have reviewed.

http://www.isaserver.org/tutorials/ISA-2006-Firewall-Web-Publishing-Rules.html

If this is already covered in earlier discussions please point me to it. My searches returned only two results for reverse proxies.

If there is any information on exploiting weaknesses in reverse proxies that will also be helpful.

Thanks in advance.

Cheers.
