- Squid did not properly release allocated memory when generating error page contents, which caused memory leaks. Consequently, the Squid proxy server consumed a huge amount of memory within a short time period. This update fixes this memory leak and Squid no longer consumes more memory than expected.

Bug Fix
- BZ#810115
- Previously, Squid did not pass the ident value to a URL rewriter that was configured using the "url_rewrite_program" directive. As a consequence, the URL rewriter received the dash character ("-") as the user value instead of the correct user name. The underlying source code has been modified so that the URL rewriter now receives the correct user name in the described scenario.

Bug Fix
- BZ#815682
- Squid used as a transparent proxy can only handle the HTTP protocol. Previously, when using Squid as a transparent proxy, it was possible to define a URL in which the access protocol contained the asterisk character (*) or an unknown protocol namespace URI (Uniform Resource Identifier). As a consequence, an "Invalid URL" error message was logged in the access.log file during reload time. This update ensures that "http://" is always used in transparent proxy URLs, and error message is no longer logged in this scenario.
