Subject: Slice filter: fetch slices in cloned subrequests.
X-Git-Tag: release-1.11.10~4
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=b9a031622b7bf586a9c724dade16abfac188f2f2;p=nginx.git

Slice filter: fetch slices in cloned subrequests.

Previously, slice subrequest location was selected based on request URI.
If request is then redirected to a new location, its context array is cleared,
making the slice module loose current slice range information.  This lead to
broken output.  Now subrequests with the NGX_HTTP_SUBREQUEST_CLONE flag are
created for slices.  Such subrequests stay in the same location as the parent
request and keep the right slice context.
