SPLongOperation and server cannot set content type after http headers have been set

    Question

  • Hi,

    I get errors of the type server cannot set content type after http headers have been set. I am using splong operation (with the using blocks etc), and within this, I use HTTPResponse to transmit a file (zip file for download). Is there a reson i.e. with the internals of splongoperation, that this cannot work? Does splongoperation send a http response? Also, is it possible to perform two or more httpresponses on the same page?


    Thanks
