The main issue is that the original rulesets would apply line by line
regardless of the type of line (start line, header, etc). This is the
reason why it was so painful to use for URL mapping, and so slow!
Imagine that when a request comes from H2, we have to emulate them by
recompose a fake H1 request representing approximately the same contents
and iterate the regex on each line there. It's really ugly, extremely
slow and unreliable. That's why I'd rather have new actions to edit the
URI, path and whatever is needed instead.
Cheers,
Willy
