Symptoms

Server-side flows are not reused. In this version of the software, the system disables reuse of server-side flows if the server-side flow is established without use of a pool.

Impact

This causes virtual servers that do not use pools to create a new server-side connection for every HTTP request, which results in excessive back-end connection traffic.

Conditions

This occurs when using HTTP OneConnect on wildcard non-translating virtual servers.

Workaround

For all virtual servers except for APM virtual servers, you can use the following iRule to reuse connections: when HTTP_REQUEST_RELEASE { if {[HTTP::request_num] == 0} { ONECONNECT::reuse enable } }

Fix Information

None
