RFC2616 - content-disposition with special characters - Problem to export file

Hello people.

 

I have one problem

 

I am having problems to export a excel file, bigger than 96K. When the file is smaller than 96K the problem dosent occurs, but with files bigger than 96K the F5 send a reset packet.

 

In SOL5922 : Error Message: http_process_state_prepend - Invalid action EV_INGRESS_DATA during ST_HTTP_PREPEND_HEADERS

 

I identificated this erros, The sol said that Any response that is not compliant with RFC2616 causes this error message.

 

In a Httpwatch a can see that in content-disposition there is special characteres like example:

 

content-disposition= attachement;filename=FILE_teste_01/01/2001 10:08:01.xlsx;size=196...

 

Probably these special characters in content that is not compliant with RFC2616.

 

if that behavior can not be corrected the application side, can I solve that with some irule? irule Replace content can resolve? If someone can quote some example that would answer thank you very much

 

thank you very much

    Hello

     

    The cause of the problem, is like the SOL said, a back end answer that not compliance with the RCF.

     

    We are analyzing the tcpdump captures and httpwatch.

     

    Until this moment we identify one beahvior. content-disposition there is special characteres like example:

     

    content-disposition= attachement;filename=FILE_teste_01/01/2001 10:08:01.xlsx;size=196...

     

    Probably these special characters in content that is not compliant with RFC2616.

     

    if that behavior can not be corrected the application side, can I solve that with some irule? irule Replace content can resolve? If someone can quote some example that would answer

     

    thank you very much

    You can turn off HTTP processing altogether by either removing the HTTP profile from the virtual or using the HTTP::disable command in an irule after connecting to that server.

    In my scenario I have no irule.

     

    Only a VS with http profile and cookie persistence
