Above is a packet sent by webapp server to client via PTP mode SSL VPN(MAG6611)

After the webpage running on the client received the packet, it goes directly to http://replacetherealdomain.com/welcome.html not as expected as http://sslvpndomain.com:11002/welcome.html

the domain http://replacetherealdomain.com is already on the PTP replace list and was redirect to http://sslvpndomain.com:11002

So is there a configure to replace the link on the parameter section in a packet? Or is there an alternative method to this problem?

Thank you!

It may be an application that cannot handle the changes done by passthrough proxy.
What do you have enabled to be rewritten in the passthrough proxy policy?
Why are you using passthrough proxy rather than standard rewrite?
Do you have custom headers enabled (Users>Resource Policies>Web>Rewriting>Custom Headers)?

thanks for your reply!

the application handle the change just fine

as for the rewriting configure, everything was left default except certain domains with 80 and 443 port set to be rewritten.

I looked into your last advise but the link is not in the header section but parameter section.
is there any chance than the parameter section can be filtered and replaced either?
