CirrusCRLF after HTTP/1.1
Hi .
I have a lagecy java app that does not include CRLF after protocol version .
How can I add it in an irule through F5
MAbbasIt's a post request
POST /abcde HTTP/1.1 need a CRLF here
Update - i can see it in binary scan that it smissing a Carrage Return --
but if I try and update HTTP::request - it gives me an error
POST\x20/abcd\x20HTTP/1.0\x0a
Thanks

i have done a find and replace in TCP -- CLIENT_DATA
regsub -all "\n" $packetdata "\r\n" packetdata
and done a Payload Replace
it seems to work --
does any one have a better idea ? or a better implementation ..

Dear Abbas,
I was going to offer you the solution that you put in place. however it should be optimized to the maximum by applying rewrite only on very specific URLs.
I don't see how we can do otherwise without rewriting the payload ...
Haven't you try or modifying the Java application? it would be easier to correct the problem at the source.
keep me in touch if sou need help for irule ...
regards

Thanks fro the reply youssef -
yes - i have a if condition that selects the URL -- to update
Question -- is there any way this can be done in http
i tried doing a replace in HTTP::request -- but it does not allow me to update in that

MAbbas - Do you have the complete iRUle you used that worked? I am facing a similar issue but have not been having any success.
