RAM cache statistics has more http/1.0 responses

Hi All, I have a vip which has a ram cache & wam(http class) associated with it. There are plenty other vips similar in my LTM. But only one particular vip has more of http/1.0 responses. I have checked it and the server is responding with http/1.1 responses itself. When checked with a websniffer, even for http/1.1 requests the site is responding with http/1.0 responses. Not sure if there is anything which i need to check specifically to modify this behaviour.

 

Anybody has any idea about this. Current LTM version 10.2.4 HF11(i know its very old.)

 

Statistics of ram profile(problem): | requests (total, max in conn, GET, POST) = (1.440G, 54393, 1.434G, 1.507M) | requests (v0.9, v1.0, v1.1) = (1.739M, 4.595M, 1.433G) | responses (v0.9, v1.0, v1.1) = (1.765M, 30.74M, 24.34M)

 

Other ram profiles(good): | requests (total, max in conn, GET, POST) = (853.6M, 149935, 853.6M, 35649) | requests (v0.9, v1.0, v1.1) = (586, 1.996M, 851.6M) | responses (v0.9, v1.0, v1.1) = (0, 2.047M, 122.9M)
