Path Blocking with Metacharacters

[cattleyavns]

My lastest experimental about webbugs blocking, this filter will check if a URL contains something like:

Code:

http://12.123/2?=tttttttttttttkkkk&1?=[color=#FF0000][b]0C92C3423CA7811A61745F7ED2F6A01[/b][/color]3

Some websites generate MD5 (32 chars) or SHA1 (40 chars) based on our information (user-agent, plugins, date and time, timezone...) using Javascript and then send to their server and log our information, so this is a very simple method to block their tracking method, this is a variant of webbugs.

Code:

/.*?=(?:.{32}|.{40})(?:$|&)

Like my /.{300} above, use this filter carefully.
