java application issue with ASM
Folks
i am facing issue with application which use java client over F5 ASM but some reasons were are getting 501 response towards client does anybody face similar issue if i remove the asm policy application works fine, what i observed is multiple cookie has been inserted by ASM then application is not working any thoughts?

ASM only allows GET, HEAD and POST request methods. 501 Not Implemented suggests the client is sending a request with a different method. Can you confirm this? If you do a packet trace, httpwatch/fiddler etc. do you see any methods being used other than the above?

Hi Nathan
Thanks for your comments , I have checked from tcp dump java client doing POST request only also I have opened TAC case as per TAC application is not supporting the request when multiple cookies exist in the response ( ASM inserting additional cookie along with server cookie) which cause client sending reset to LTM/ASM when i remove the ASM policy in LTM observed only server cookie exist and application working fine without any issue.
any thoughts on this?

I have faced the similar issue when running program version is Java on Azul Zulu JRE version 1.8.0_172 at Windows 10 or Windows Server 2016.
Does anyone know how to fix it ?
Thanks.
