How to verify WSA Web Caching functionality

[pemasirid]

Hi,

We have WSA C380 with software version 9.0.x and we want to verify the performance or the functionality of web caching feature. It is not output of Ipchek and get the proxy cache capacity. 

Is there a way to verify or make sure caching functionality is working properly such as that user already accessed web site will get loaded from local WSA and not getting from internet when he access 2nd time.?

thanks

Log in to the appliance and use the "rate" command.
You will see output like this:

 %proxy reqs                   client server %bw disk disk
 CPU   /sec hits blocks misses kb/sec kb/sec saved wrs rds
 14.00 146 177 49 1241 11437 10036 12.3 312  64
 13.00 181 170 67 1581 16518 14109 14.6 434 195
 14.00 110 138 28  943 11825  9847 16.7 309 153
 12.00 121 126 69 1019 63759 62431  2.1 389 159

The hits colum and %bw saved column will tell you if the appliance is caching.

You can also grep the access logs for "TCP_MEM_HIT" or "TCP_HIT", which will show you which requests that actually hit the cache.

Hi Erik,

Many thanks for your reply on this while the information you provided really help to get web cache functionality I am just wondering if there any GUI report option which we can see in clear graphical manner.?

Thanks again for your response.

Hello Pemasiri,

Currently there is no graphical report in WSA. However you could find the summary report in WSA GUI as attached. Hope it helps.
