HTTP send string limit

Hi,

 

I am attempting to monitor OCSP responders using an actual OCSP request via a custom monitor using HTTP as the parent monitor.

 

In a few other posts I've seen external monitor solutions that use "openssl ocsp ..." as a solution. This will certainly work. But, our LTM is heavily used and I'm concernced about resource utilization on the device. External monitors aren't nearly as efficient.

 

An HTTP health monitor will only look at the first 5120 bytes of an HTTP response. I need to discover what this limit is on the send string.

 

An HTTP send string appears to only support 100 bytes. I determined this by doing a tcpdump on the monitor and only seeing 100 bytes of a 185 byte string that was entered. (full packets were captured)

 

Is there a 100 byte limit on the size of the send-string, or is there some other problem? If so, can it be expanded? Has anyone else tried to do what we're trying to do?

 

We are using version 11.6.

 

I'm new to DevCentral and hope I haven't missed this answer somewhere else.

 

Thanks!
