Great filters...

[Siamesecat]

The filter I really appreciate from the time when this forum was hosted by Lycos were the cookie filters that filtered by content of cookie.

Code:

[HTTP headers]
In = FALSE
Out = TRUE
Key = "Cookie: Filter Cookies (out)"
Match = "?&(\#([^;]++$LST(CookieValues)[^;]+)\2$SET(cookie=[ \2 ] $GET(cookie))(;|))+\#"
Replace = "\@"

In = TRUE
Out = FALSE
Key = "Set-Cookie: Filter Cookies (in)"
Match = "?&(\#([^;]++$LST(CookieValues)[^;]+)\2$SET(cookie=[ \2 ] $GET(cookie))$LOG(!WCookie Filtered: $GET(cookie) - \u )(;|))+\#"
Replace = "\@"

The blocklist was called Cookie-Values.txt. Here it is:
# Proxomitron4 URL killfile: $LST(CookieValues) | Cookie Values.txt
# NoAddURL
#
# "Set-Cookie: Filter Cookies" uses a recursive match to remove the
# following entries. This is so multiple entries can be removed at
# once. This filter does not block the cookie if the below values are
# found. It only removes the value from the cookie.
# Basically, the match is pretty simple..
#
# *$LST(CookieValues)*
#
# So, if you add "ID" to this list,
# ID, DID and IDIOT would match.
# It is very important to be precise with the entries you add. ;)
#
# Below are some examples of what kind of values you can filter
#
# Example sites:
# www.ddimagazine.com/
# ecommercetimes.com/
# ign.com/
# www.indexstock.com/
# www.news24.com/
# www.salon.com/
# www.securityfocus.com/
# techtv.com/

# Also note, existing cookies are not filtered for Set-Cookie.
