[whenever]

This is a filter discussed and developed in this topic, I post it here in case other people may find it useful.

Thanks z12 and lnminente for their help.

Code:

[Patterns]
Name = "Add cache links to Google cache results page {whenever,ln}081011"
Active = TRUE
URL = "$TYPE(htm)[^/]+/search\?*q=cache"
Bounds = "<a\s*</a>"
Limit = 256
Match = "$URL(*cache(:|%3a)(http(://|%3a%2f%2f)|)([^/&]+)\1*)"
        "(*href=$AV(http://$TST(\1)/\2|/\2)*)\3"
Replace = "\3<a href="http://www.google.com/search?q=cache:http://\1/\2"><img src="http://www.google.com/favicon.ico" style="border: none;" /></a>"
