Disable Symantec Blue Coat ProxySG caching
Step-by-step guide
To prevent the transmission of stale content or other issues caused by object caching, you can use either cache(no) or bypass_cache(yes) in content policy language (CPL). For a comparison of cache(no) and bypass_cache(yes), see KB1772.
This sample provides instructions for disabling object caching for specific URLs by adding a policy rule in the Web Access Layer.
-
In the Management Console, select Configuration > Policy > Visual Policy Manger, and then click Launch.
-
From the Visual Policy Manager (VPM) dialog box, select Policy > Add Web Access Layer. The Add New Layer dialog box appears.
-
In the Add New Layer dialog box, name the layer to reflect the purpose of the layer, such as "Web Access Layer (bypass cache)," then click OK.
-
Right click the Destination field and select Set from the drop-down list.
-
In the Set Destination Object dialog box, click New > Request URL, and enter the URL you want to exclude from the cache. Click Add, then OK.
-
Right click on Action and select Set > Bypass Cache. Then, click OK.
-
Click Install policy to apply the new policy.
To use CPL code for the same policy rules, add the following CPL code in the local policy file or in a VPM CPL Policy Layer:
<Proxy>
url.domain=<url> bypass_cache(yes)
In the example above, <url> is the URL you want to exclude from caching.
