We have a FortiGate 100D Cluster (Active-Active), running Version 5.2.2 Build 642 (GA). We have several IPv4 Policies permitting access to the Internet from several different subnets. On each policy we have Web Cache enabled.
However, when I look at the Cache Monitor in WAN Opt & Cache, I see No Data, indicating that nothing is being cached. Could someone please give me some pointers on what I should look at next to troubleshoot this issue.
Just a quick update on this issue. Unfortunately, despite their best efforts, Fortinet Support were unable to supply a solution. Their final recommendation is to re-image the appliances with the latest firmware version (5.2.2) or wait for version 5.2.3 which should be released "by end of February".
even after machine reboot ... WEB CACHE still shows no data. After reboot the Traffic Shaping begin to show real shapers ... during installation I setup more and machine get crazy and not sowing up but after reboot shapers graphics are ok.
only WEB CACHE is making problems. what do we do ?
Just a quick update on our situation here. We ran a firmware upgrade and are now operating the 100D Cluster on Version 5.2.3, Build670 (GA).
After the upgrade web caching was still NOT working.
However, I created a WAN Opt. Profile for HTTP, Byte Caching only and applied this to a test IPv4 policy. Now I am seeing hits in my Cache Monitor where previously it had stated 'No Data'. I'm also seeing that space allocated to WAN Optimization & Web Cache is now being used (System > Config > Advanced - Disk Management).
To say I'm confused is an understatement. My understanding was that, to enable web caching, it was simply a case of switching on Web Cache within the IPv4 policy. No mention was made of creating a WAN Opt. Profile.
Has anybody any suggestions as to what may be happening here? Is there a field somewhere within a log file which may indicate that content has been returned from cache and not the Internet?
Also, please feel free to point out if I'm being an idiot in regard to this issue, constructive criticism is always welcome!!
