Hi The health monitor looks li this: GET http://127.0.0.1:8083/heakth.app.filtering HTTP/1.0\r\n\r\n Why is the IP address 127.0.0.1 ?
Jonathan_Kneph1Hello etrust. The health monitor uses that specific proxy request in order to test the proxy, and it's required internal management functions, such as the filtering service. Checking just the proxy port wouldn't assure that filtering is working, and checking just the filtering service wouldn't assure that the proxy is working.
Sidoli_236736Hi, we have a scenario where we require iRule functionality while using this iApp. We need to decrypt the traffic before it is sent to Websense so that iRules can process the request. If we create the clientssl profile with a certificate and key then we can successfully achieve this, however the browsers rightfully complain because there is a certificate name mismatch for the target web server, do you know how we can accomplish this?- vrn_159121

Sidoli, F5's SSL forward proxy functionality will address your issue: https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-11-3-0/14.html. With this option the F5 will generate a valid SSL certificate for the requested website.
