http_process_state_prepend - Invalid action EV_BODY_COMPLETE during ST_HTTP_PREPEND_HEADERS

Anyone know what this error message is all about?

 

 

http_process_state_prepend - Invalid action EV_BODY_COMPLETE during ST_HTTP_PREPEND_HEADERS

 

 

The rule i'm using is:

 

 

WHEN HTTP_REQUEST {
   if { (HTTP::uri] starts_with "/exchange") } {
   pool OWA-pool
   log local0."test1"
   }else{
   pool Content
   log local0. "test2"
   }
}

 

 

When I enter the URL https://xyz.com I see entries in the log for "test2" - as expected.

 

 

When I enter the URL https://xyz.com/exchange/ I see entries in the log for "test1" and the above error message, but DON'T see the expected content..

 

 

I've tried searching here, Google, and F5, but couldn't find anything..

 

 

'Status code' for the error is 011f0007, if that helps..
