LTM maintenance page when all members disabled (v13)

Hi!

 

Here comes a question regarding LTM and the delivery of maintenance pages via iRule if all pool members are disabled:

 

As described in article K86025623 the LTM virtual server behaviour was changed in version 13.0. If all pool members are disabled, LTM will immediately answer the client´s SYN with a RST. There is no chance to insert an iRule action there because there won´t be a TCP session and hence no HTTP request to trigger on.

 

The old behaviour allowed LTM to establish a full TCP session, so an iRule event could be triggered to deliver a maintenance page to the client. Does someone know a workaround or solution to keep the old behaviour?

 

Best regards, Peter.
