Ignore content-type while forwarding to backend proxy

[Roland RoLaNd]

thank you for the advice!
i tried doing that before though it did not work so i thought there could be another solution..in any case tried that again, set it right before the proxypass condition and it's still passing the type through...may i show u my config to see what might be overrirding that ?
