Bug ID: 59744
Summary: AH00717: Premature end of cache headers
Product: Apache httpd-2
Version: 2.4.10
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: mod_cache
Assignee: [email protected]

entity headers file after a GET
Every once in a while I can see this error message popping-up in my logs:
> AH00717: Premature end of cache headers
So far I didn't see actual "bad" consequences other than the error message
itself.
To reproduce it, it's enough to
POST twice to an already cached resource.
More information and guesses in this thread:
https://mail-archives.apache.org/mod_mbox/httpd-users/201606.mbox/%[email protected]%3E
Current best guess is that the first POST creates an invalid entity on which
second POST hurts.
Background: When mod_cache is used, POST are expected to be ignored.
Since this commit:
https://github.com/apache/httpd/commit/dea98c9bf110c149e7e0af381221ba09fdc52d0c
This hunk was introduced:
> "PUT/POST/DELETE: Adding CACHE_INVALIDATE filter
although I couldn't spot more precisely what could be wrong.
Attached are the entity header file after a GET request, and then after the
(cache invalidating) POST request.
