Default SSL session cache size of ProxySG, ASG and SWG VA
Last Updated September 27, 2018
Determine the default SSL session cache size for each ProxySG, ASG or SWG VA appliance. After increasing SSL session cache by following TECH247135 you want to revert to original SSL session cache.
Default SSL session cache size depends on total available RAM on the appliance. For ProxySG Appliances with
1. SWG VA V100 with 4GB RAM 5,369 2. SWG VA V100 with 8GB RAM 8,113 3. SG9000-5 - Only supports 4GB RAM - and session cache size is 6,989 4. SGOS 6.7.1.x / 6.7.2.x / 6.7.3.x for most devices session cache size is used as half of the size mentioned above to reduce overall memory usage. This will be reverted back again on 6.7.4.x and later versions.
For Advanced Secured Gateway(ASG) Appliances total amount of RAM is being shared between Proxy and CAS. SSL session cache default size is determined based on how much is allocation for Proxy.
Total installed RAM on ASG appliance can be found under https://x.x.x.x:8082/sysinfo --> under section /Diagnostics/Hardware/Info
To view how much is allocated or proxy Navigate to web UI of ASG --> proxy --> Maintenance --> Systems and Disks --> Summary --> Memory installed
For example ASG-S400-20 has total 24GB memory installed. For proxy 16GB is allocated. Hence SSL session cache default size would be 41,894
