Victor Julien	89f83e714c	Introduce http_server_body keyword. ... The http_server_body content modifier modifies the previous content to inspect the normalized (dechunked, unzipped) http_server_body. The workings are similar to http_client_body. Additionally, a new pcre flag was introduced "/S". To facilitate this change the signature flags field was changed to be 64 bit.	14 years ago
Anoop Saldanha	17f3f36d38	packet keywords only added for packet mpm. Rest in stream mpm. Update detection engine to handle the same	14 years ago

Eric Leblond	0c34a1c5e7	rewrite constants and add flag for replace ... This patch make use of bit shift to rewrite some of the mask constants. It also delete an unused flag value and suppress the associated dead code. The numeric value of the flag is now used by the flag needed for replace code.	14 years ago
