Hi All ,
We are experiencing the below given error message in the servers which are kept before the cisco ACE .
“ ………………….,Backend Response=503 Service Unavailable,Backend processing time=17,Processing time=21 “
Any stcky configuration has not been enabled on the server farm where we kept the Rserver . Also we can see the live connection on the
Rserver through the loadbalancer.
But the probe configuration is as a below.
probe http TCP35812_HTTP
port 35812
interval 5
faildetect 2
passdetect interval 2
request method get url /esales/is_available
expect status 200 200
connection term forced.
The server team confirmed as there is no issue at their end and it is working fine if they access without the loadbalancer ( VIP).
Please suggest me what is the “ request method get url /esales/is_available “ . Also suggest me is it related to loadbalancer or server related issue .
Regards,

Hi,
Have only one server in the serverfarm and see if it fixes your problem. If the problem still persist with one server, then most likely this is not a loadbalancer issue.

Hi,
Try'n have a look at this, I think you will find it useful.
But in short, when applying e.g an http-probe to your serverfarm, you can specify a request method (GET og HEAD) to request specific content from the rserver using http. Combined with either http response-code check or regex, this provides for more detailed availibility information on the specific rserver.

You probably have to forge a whole HTTP header for your probe (Host field)

Hi Surya/Siva,
Thanks for the response .
Could you please elaborate me how this request method “request method get url /esales/is_available “ in the above probe can be replaced with the “forge a whole HTTP header for your probe “ ( The suggested method )
