What are HTTP and the HTTP Proxy?
HTTP (Hypertext Transfer Protocol)
is a protocol for sending and displaying files (text, graphic images, sound, video,
and other multimedia files) on the Internet. The HTTP Proxy is a high performance
content filter. It examines Web traffic to identify suspicious content, which
can be a spyware, malformed content, or another type of attack. It can also protect
your Web server from attacks from the external network using protocol anomaly
detection rules to identify and deny suspicious packets.
You can configure the HTTP Proxy to:
Only allow content that matches RFC specifications for Web server and clients
Restrict the content the Firebox allows into your network, based upon fully a qualified domain name, path name, file name or extension as it appears in the URL.
Restrict the content the Firebox allows into your network based upon MIME type.
Block downloads of any unique file type, including client-side executable files like Java and ActiveX, by file header (hexadecimal signature) pattern match.
Examine the HTTP header to make sure it is not from a known source of suspicious content
The HTTP proxy operates between the sending Web server and your receiving Web client. It processes the HTTP protocol line-by-line for any potentially harmful content before sending it to an internal Web client. It also acts as a buffer between your Web server and potentially harmful Web clients by enforcing HTTP RFC compliance and preventing potential buffer overflow attacks.
When you add an HTTP proxy policy to your Firebox configuration, you get access to two proxy actions that are included with the product: an HTTP server ruleset template and an HTTP client ruleset template. You can use these rulesets without changing them or you can use the rulesets as a base for a ruleset to meet the needs of your organization. This module shows you how to customize the rulesets in these two proxy actions.
The HTTP-Client proxy action is configured to give comprehensive protection to your network from the content your trusted users download from Web servers. An optional extension to the HTTP-Proxy (WebBlocker) is available to control the categories of Web sites trusted users are allowed to browse to at different times of the day.
The HTTP-Server proxy action is configured by default to allow most HTTP connections through to your public Web server, but stop any attempts to put files on your Web server or delete files from your Web server.

You may see references to four different types of proxy servers:
This type of proxy server identifies itself as a proxy server and also makes the original IP address available through the HTTP headers. These are generally used for their ability to cache websites and do not effectively provide any anonymity to those who use them. However, the use of a transparent proxy will get you around simple IP bans. They are transparent in the terms that your IP address is exposed, not transparent in the terms that you do not know that you are using it (your system is not specifically configured to use it. )
This type of proxy server identifies itself as a proxy server but does not make the original IP address available. This type of proxy server is detectable but provides reasonable anonymity for most users.
This type of proxy server identifies itself as a proxy server, but make an incorrect original IP address available through the HTTP headers.
