Tinyproxy

A problem with the filter initialization code when comments appeared on the first line has been fixed. In addition, the ability to escape the comment character was added. A problem with the installation of the HTML error pages has also been fixed.

An off-by-one error in the MaxRequestsPerChild directive has been fixed. An assert has been removed from the debugging realloc() function since a NULL pointer is allowed by the realloc() spec.

This release adds both bugfixes and feature enhancements. The two
biggest changes are the additions of dynamic HTML error-handling code
(which allows the HTML error messages to be template-driven) and
expanded upstream proxy support (allowing different proxies to be
used, based on the request). In addition, there have been numerous
bugfixes to work around some broken clients (IE's POST method, for
example), and broken servers (which do not follow the HTTP
specification correctly). All users of tinyproxy are encouraged to
upgrade to this release.

PID and log files are handled correctly now, and more error messages are produced when problems occur. TCP tunnel capabilities were removed. A fix was made for a problem with the actual connection relaying portion of the code---this was an edge case, so most people would not notice the problem. tinyproxy should now compile cleanly on OS X. A new directive was added to control the Via HTTP header. A problem with embedded user names and passwords in the URL was also solved.

The DNS caching system has been removed. HTTP standards compliance has been improved, and and all websites should work properly (for example www.heise.de). There are new security related directives for the CONNECT method. A ton of memory leaks were fixed, as well as a problem where memory would be freed twice. A bug in the log rotation code which could cause log file corruption has been fixed. Code which closed a socket twice (leading to undefined errors) has been removed. A SEGFAULT in the tunnel code has been fixed.
