svn commit: r1773158 - /httpd/httpd/branches/2.4.x/server/protocol.c

[wr...@apache.org]

Author: wrowe
Date: Wed Dec  7 22:54:36 2016
New Revision: 1773158

URL: http://svn.apache.org/viewvc?rev=1773158&view=rev
Log:
As noted by rpluem, r->protocol isn't const char *. Ensure the exit cases
are pstrdup'ed. Note that r->protocol = "" is not in a return path.

Simplify the garbage-in protocol handling without consideration to 'strict'
settings. It is expected to be caused by an invalid raw SP in the URL.
