Slow response with SSL (https) on CSS

Hi,

Our network topology is as per the attachement “CSS Topology Diag.jpg”. The users behind the CORE network will access the application through the VIP address “192.168.10.171”. SSL card has been installed on the CSS's and the SSL gets terminated on the CSS. The traffic between CSS and the physical servers are on “http”.

Now when the users tries to access the application using SSL (https://192.168.10.171) the application response is very slow, however when the users tries to access the application using http (http://192.168.10.171) application response is ok.

Find the attached configurations of the primary and secondary CSS. Any inputs to resolve this issue..??

(Note: It take nearly 20 - 30 seconds to get the page when users initiate a connection through https and however when the users initiate the http connection page gets displayed in 2 - 3 seconds)

Regards

Re: Slow response with SSL (https) on CSS

Try the following commands

ssl-server X ssl-queue-delay 0

ssl-server X tcp server ack-delay 0

ssl-server X tcp virtual ack-delay 0

If the problem persists, get a sniffer trace on client side and server side simultaneous.

Re: Slow response with SSL (https) on CSS

the traffic having issue is HTTPS not HTTP.

So we want to see a trace with HTTPS.

Also, get the trace on the client and on the server - not the CSS. (we want to see both side of the css)

Re: Slow response with SSL (https) on CSS

Hi Gilles,

I have attached the https logs in my previous reply to this post.

And regarding the server side trace, I will post it soon... however just to mention the ssl traffic (https)gets terminated on the CSS and from the CSS to the servers it is http traffic....

Re: Slow response with SSL (https) on CSS

there is absolutely no SSL/HTTPS traffic in the 2 traces you sent. Only HTTP.

I would expect your client trace to contain SSL traffic.
