Anon Proxy Server 0.99
Anon Proxy Server is a fast http, https, socks caching proxy server. more>>
Main features:
- Easy Configuration - Web based, no editing text configuration files.
- Memory - No big databases are kept in memory, no matter how large the cache is, memory usage will only increase when more users access it at the same time.
- Speed - To see how much cpu the proxy uses, run top or task manager. Then open multiple windows and hit reload continously, on my computer I usually run out of bandwidth before it goes near 3-5% cpu usage.
- Shared Cache - Can be used as a general cache for all users of a computer/network instead of one cache per profile.
- Automatic config - Auto generates the .pac file for automatic proxy settings, no more updating in the do not use proxy section of individual users browsers.
- Anonymous P2P proxy - Joining the anonymous proxy network will allow you to use other peoples proxys for browsing and allow them to use yours.

Enhancements:
- The program now checks for errors in access configuration.
- Variable timeout values were added.
- Log rotation was fixed.
- Occasional crashes on a bad URL were fixed.
- The auto configuration .pac file was fixed, so it should work even if the proxys URL was not set properly.
- Anon proxy defaults to 3 keys now for more reliability.

Yet Another Filter Proxy 0.1.1
Yet Another Filter Proxy project is a preforking, banner filtering, content scanning Perl proxy. more>>
Yet Another Filter Proxy is a proxy to filter out advertising banners and malicious script code from web sites. It is written in Perl and based on an example by Randal L. Schwartz.
For performance reasons it uses preforking to spawn several processes of itself (like Apache does).

HTTP Server type 1.2.3
httptype is a program that returns the http host software of a website. more>>
httptype reads a list of http hosts and optionally the port number for each of these. It queries each host, displaying the type of HTTP server running on that host. It reads the http_proxy and no_proxy environment variables to determine whether to use a proxy or not.
httptype reads a list of http servers and, optionally, the port number for each of these. It then queries each of the hosts and displays the HTTP server software of the host.
Input may be read from a host file if specified using the --hosts switch:
httptype --hosts [hostfile]
If hostfile is omitted or `-, httptype reads from standard input. See Format of host file for more info.
A single host may be queried by passing its name on the command line:
httptype host [port]
If port is omitted, 80 is used.
If no host file is specified through the --hosts file and no host is specified on the command line, httptype will read the list from standard input. See Format of host file for more info.
httptype will read the http_proxy environment variable and try to determine if a proxy server is being used. This setting may be overridden using the --proxy switch:
httptype --proxy proxyhost[:proxyport]
If proxyport is omitted, 80 is used.
If the proxy server is `none, no proxy is used. This is typically used to prevent httptype from using the proxy server specified by http_proxy. The --noproxy switch can be used to achieve the same.
Additionally, you may use the no_proxy environment variable to specify a comma delimited list of hosts for which httptype should not use the proxy. If httptype comes across any of these hosts, it will make a direct connection to them.

- made 1.3.8 stable and renamed to 1.2.3
