# HTTP - HyperText Transfer Protocol - RFC 2616

# Pattern quality: great notsofast

|
# Usually runs on port 80
|
|
#
|
|
# This pattern has been tested and is believed to work well. If it does not
|
|
# work for you, or you believe it could be improved, please post to

# this intentionally catches the response from the server
|
|
# rather than the request so that other protocols which use
|
|
# http (like kazaa) can be caught based on specific http requests
|
|
# regardless of the ordering of filters...
|
|
# also matches posts
|
|
|
|
# Sites that serve really long cookies may break this by pushing the
|
|
# server response too far away from the beginning of the connection. To
|
|
# fix this, increase the kernel's data buffer length.
