WAE-512- Cache / Proxy Prevents access to some https sites
We have our desktops going through a Cisco Wide Area Applicaion engine with the intent of using this as a web cache. We have successfully used it as a cache. However, when we go to some https secured sites we get an error page from the cisco device:
The requested URL could not be retrieved.
The following error was encountered:
The request was rejected because the port it was connecting to
is not configured to receive the protocol being sent.
Please contact your network administrator.

We have all desktops configured through IE, in the following:
"Use the same proxy server for all protocols" setting is checked.
We also did the following at the cache server interface:
1. Log in to the Cisco Content Engine through the GUI interface.
2. Go to the Caching tab and click on âHTTP Freshnessâ. Â For Cache non-image
objects sent with cookies select âyesâ. Â Â
3. The Maximum size of a cacheable object should be set to at least 200000 KB. Â Â
4. After that is done, click on âupdateâ.
5. Next, go to the Caching tab and click on HTTPS Proxy. Â Make sure that Enable
HTTPS Proxy is set to âOnâ and that the ports 443 and the proxy port you
previously configured in Step 29 above, usually 8080 or 80 are listed with a space
between each port. Â When this has been done click âupdateâ. Â Â
