Recently we noticed that some sessions (not all) that contain HTTP requests with an IP address in the "Host" header are not getting populated with the alias.host meta. My question is: how does the HTTP parser decide what value to assign to that meta? Also, is this common or expected behavior?
If it helps, many of the sessions with this issue are very simple. A completely fabricated, but syntactically accurate example:
POST / HTTP/1.0
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Win32)
All of this is happening on the latest 9.8 stack. Not all sessions on each decoder are affected. Thanks in advance for your help.
