I recently "inherited" a CSS 11503 - I've only used ACEs before - and I want to get HTTP keepalives working.
To start, I created a test service:
lb-1# show run service sunbird-http-7025-test
!************************** SERVICE **************************
service sunbird-http-7025-test
port 7025
ip address 141.211.229.168
keepalive type http
keepalive uri "/render.userLayoutRootNode.uP"
keepalive http-rspcode 302
active
And verified that the server is indeed returning a 302 response:
lb-1# llama
lb-1(debug)# icp probe service sunbird-http-7025-test "/render.userLayoutRootNode.uP"
Probing 141.211.229.168:7025(-) Probing via HEAD
IP Address: 141.211.229.168
Port: 7025
URL: /render.userLayoutRootNode.uP
HTTP Version: 1.1
Server Model: Not Present
Server Date: Wed, 30 Nov 2011 15:05:22 GMT
HEAD Response: 302 Moved Temporarily
Location: http://141.211.229.168/Login
HEAD Support: Yes
Persistence: Yes
Keep-Alive: Yes
Request Depth: 100
TBR: 5
Connect Time: 4 ms
Rqst/Rsp Time: 1 ms
Pipeline: No
SSL: No
but the service won't come up:
lb-1# show service sunbird-http-7025-test
Name: sunbird-http-7025-test Index: 26
Type: Local State: Down
Rule ( 141.211.229.168 ANY 7025 )
Session Redundancy: Disabled
Redirect Domain:
Redirect String:
Keepalive: (HTTP-7025:HEAD-302:/render.userLayoutRootNode.uP 5 3 5 )
Keepalive Error: General failure
Any/all assistance would be appreciated!

Hi Kurt,
What WebNS version are you running on that CSS? Do you have any other "class A" keepalives working (HTTP keepalives) correctly on that box for that or any other service?
This seems to be related to a known bug, the fact that ICP probe returns a correct status almost confirms my suspicion.
Tnx

This is the only http keepalive we have configured with a non-default
configuration (i.e. the only one with a keepalive uri and response code);
we have others that also use non-standard ports, and these work - e.g.:
lb-1# sho keepalive AUTO_calliope-8080
Name: AUTO_calliope-8080 Index: 7 State: Alive
Description: Auto generated for service calliope-8080
Address: 141.211.229.202 Port: 8080
Type: HTTP:HEAD:/
WebNS version? I hope you mean the SW on the box, this is the first time
I've heard of "WebNS"...
It's running 08.20.2.01
