If an HTTP request or response had a "Cache-Control" header that had
multiple comma-separated subparts in its value (like "max-age=1,
no-store" for instance), we did not process the values correctly and
only parsed the first one. That made us store some HTTP responses in the
cache when they were explicitely uncacheable.
This patch replaces the way the values are parsed by an http_find_header
loop that manages every sub part of the value independently.
This patch should be backported to 2.2 and 2.1. The bug also exists on
previous versions but since the sources changed, a new commit will have
to be created.
[wla: This patch requires bb4582c ("MINOR: ist: Add a case insensitive
istmatch function"). Backporting for < 2.1 is not a requirement since it
works well enough for most cases, it was a known limitation of the
implementation of non-htx version too]
