Subject: lib-http: client: Reset redirect counter when the request is retried.
X-Git-Tag: 2.3.9~2226
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=370753545874ea89be54dbfb52ec77dafb7bad95;p=thirdparty%2Fdovecot%2Fcore.git

lib-http: client: Reset redirect counter when the request is retried.

The absence of this reset caused problems when there was a redirect limit and
the request was retried, in which case the limit is reached too soon.
