ValdikSS	feb03c74c8	Print message of HTTP fragmentation > 2 incompatibility. We can't reliably distinguish HTTP data from other data on port 80 when fragmentation is used. HTTP method code has a special case which tries to find HTTP method when fragmentation = 1 or 2 is used, but not for other values.	8 years ago
ValdikSS	4c13435ee3	Handle Host header after User-Agent header in the HTTP packet. Fixes #29 . Most browsers would put Host header as early as they could, but not Microsoft Edge.	8 years ago
ValdikSS	ee665ee3bd	Search for HTTP methods in fragmented packets with Window Size 1 or 2. Fixes #30 .	8 years ago
ValdikSS	00e4964e73	Remove webdav HTTP methods. They are rarely used and less probably filtered.	8 years ago
ValdikSS	2fe377a23f	Do not handle traffic from private IP ranges	8 years ago
ValdikSS	b74c974235	Print error message if filter initialization fails	8 years ago
ValdikSS	96fb5f9516	Block passive DPI packets only with "Connection: close". Fixes #17 . Some servers set "don't fragment" flag and never increase TCP ID field. If they send HTTP redirection to another website, it would be blocked by the program. This is a hack to block redirects only with "Connection: close" header as presumably legal redirects are most likely would use keep-alive.	8 years ago
ValdikSS	f5ac7c0d67	Change TCP Window Size based on SrcPort, not DstPort. When HTTPS fragment size was set, the program always used it for HTTP, even if HTTP fragmentation was disabled. This is due to a bug which checked DstPort, not SrcPort, and the packets passed DstPort != htons(80) HTTPS check.	8 years ago
ValdikSS	d9e27f193c	Reimplement -s option to fix unACKed data Old code used to reduce packet size by one byte to remove space in HTTP Host header. This introduces one unACKed byte which OS later tried to send to the host. This byte was \n (the last byte in original packet) which broke POST requests. New code in this commit moves "stolen" space in the end of User-Agent header value and do not reduce packet size anymore. User-Agent value is used because not all web servers are compatible with additional space in the end of Host value. Fix #3	8 years ago
ValdikSS	c721ab0506	Always check for valid HTTP method before any modifications	8 years ago
ValdikSS	70765fa895	New option: additional space between Method and Request-URI (enables -s, may break sites)	8 years ago
ValdikSS	a2d5be1eed	const char for window size function	8 years ago
ValdikSS	30fd25bc24	Replace char* with const char* where appropriate	8 years ago
ValdikSS	9fea771d2c	Less invasive Passive DPI block. Fix #2 .	8 years ago
ValdikSS	bb05d357a7	Fix for getopt -4	8 years ago
ValdikSS	609d8aa037	New mode -3 (old -3 is now -4)	8 years ago
ValdikSS	46af3c2edb	Switch to getopt() and slightly update fragmentation code	8 years ago
ValdikSS	6b40623dce	Remove old code	8 years ago
