This patch adds support for sequencing HTTP Redirects. This enables tracking of HTTP-based redirects, which may not have a Referer header. As such, this patch also renames 'HTTP Referer statistics' to 'HTTP Request Sequences' to better reflect the more generic functionality. Note that this does not fully support RFC 3986. An external library like uriparser.github.io may be a better option for efficient, full relative HTTP URL resolution. A Sample PCAP to test functionality is available here: https://wiki.wireshark.org/SampleCaptures?action=AttachFile&do=get&target=http_redirects.pcapng A sample PCAP to demonstrate usefulness is available here: https://www.malware-traffic-analysis.net/2015/08/31/page2.html (examine request to hxxp://lk2gaflsgh.jgy658snfyfnvh.com/service.php) Change-Id: I9edd1a1de86228b0dcb1df9f6f30e24379684321 Reviewed-on: https://code.wireshark.org/review/26679 Petri-Dish: Peter Wu <peter@lekensteyn.nl> Tested-by: Petri Dish Buildbot Reviewed-by: Peter Wu <peter@lekensteyn.nl>
