Jim Gallacher resolved MODPYTHON-105:
-------------------------------------
Fix Version: 3.2
Resolution: Fixed
> mod_python.publisher should not discard content for HEAD request.
> -----------------------------------------------------------------
>
> Key: MODPYTHON-105
> URL: http://issues.apache.org/jira/browse/MODPYTHON-105
> Project: mod_python
> Type: Bug
> Components: publisher
> Versions: 3.2
> Reporter: Graham Dumpleton
> Fix For: 3.2
>
> In addressing MODPYTHON-71, mod_python.publisher code was changed to read:
> if req.method!='HEAD':
> req.write(result)
> This change should not really have been made and it should be changed back to
> what was there before, ie., just:
> req.write(result)
> This is because even when HEAD is used, any output is sent through any output
> filters before Apache finally decides to throw it away. That
> mod_python.publisher is not allowing the data through, may cause issues for
> any output filters that are doing something with the output and expect it all
> to be there.
> As an an example of an Apache module that uses output filters to do stuff,
> there is mod_cache. Luckily in that case, a HEAD request is one of various
> cases where mod_cache decides it will not use the output. This does not mean
> though that some other output filter that someone is using might expect
> content to be there for HEAD.
> In summary, one could also say that if a user wants to not output anything
> for a HEAD request, that is there decision, but mod_python.publisher should
> not be making that decision for them.
> Because HEAD didn't work before 3.2 anyway, it is possibly not essential that
> this issue be fixed before 3.2 release, but if other changes need to be made,
> it probably should.
