F5 http profile connection reset

Hi,

 

We are facing with connection reset while downloading pdf, excel file. we are getting below error

 

HTTP Unexpected server data past end of response :The BIG-IP system receives unexpected HTTP data from the server. A typical case occurs when a server sends an HTTP response with a Content-Length header value that is smaller than the actual size of the content.

 

As per support this could be due to content-length and actual data in response don't match.

 

Just a guess, f5 could be resetting connection if the http response header name is not standard? in server response there is header name and value 'MicrosoftSharePointTeamServices : xx.x.x.xxxx', in httpwatch there is warning saying 'MicrosoftSharePointTeamServices is not recognized as a standard HTTP response header. It may be spelled incorrectly or it may be a custom header that does not have a X- prefix'

 

===== How can f5 suddenly stop downloading pdf if the Content-disposition : attachment, filename=xyz.pdf is set. This will make f5 to download complete file before forwarding it to client?

 

Thanks, Sachin

  • support says the content-length and actual length don't match, have you checked that before look for other possible reasons?

     

    in principle i don't expect the HTTP profile to block things that are not "standard". you can add any header you want, the httpwatch remark should be just read as information in my opinion.
