  • Content-length and output handler


    I had big problems with my vb (2.2.9) today after my provider dated up to mysql 4 last night.

    After a long search they found the problem (thanks to them ). Please donßt ask me whats an output handler, i don´t know.

    So i just want to inform you if one of you may have a similar problem.

    From: yngve at opera dot com
    Operating system:
    PHP version: 4.3.1
    PHP Bug Type: *Compression related
    Bug description: Content-Encoding: gzip output includes the wrong Content-Length header

    I am a developer with Opera Software, the developer of the Opera browser.

    We have received several reports about problems with forums using
    VBulletin, but based on what I've learned I suspect that the problem is a
    general PHP problem, not Vbulletin specific.

    The reason for the problem turns out to be the same, or of a similar
    nature, as my earlier bug report #12884.

    A while ago I was in contact with one of the boards affected by the
    problem They reported back that they were able to solve the
    problem by turning off global compression

    From the Rage3D people (with permission):
    >The problem was caused because we were running the php "output_handler =
    >ob_gzhandler" for global site compression. vB didn't know to use the
    >right content length header. We've resolved the issue by turning off
    >global compression and enabling gzip encoding through vBulletin. We
    >will be seeing if an updated gzip library for our server will resolve
    >the issue so we can run global php compression in the future.

    The following is a hexdump of the request and response headers from one of
    my tests (before Rage3D fixed the problem).


    Best wishes
