de.businesscode.bcdui.web.cacheControl.ClientCachingFilter

All Implemented Interfaces:

public class ClientCachingFilter
extends AbstractCacheFilter

ClientCachingFilter implements client side caching.
This Filter set expires value for the within the init-parameters declared resource types.
The value is depends on the values from init-param.
Expected value must be of the type:

• ExpiresAbsTime: for absolute time
• ExpiresAbsDow: for absolute day of the week
• ExpiresAbsDatetime: for absolute date and time
• ExpiresRelDays: for relative day
• ExpiresRelTime: for relative time
• CacheRequestDirective: for native HTTP1.1 Cache-Control string

This Filter supports the exclude urls.

To exclude URLs (using starts-with matching method) add a space separated list of tokens to the parameter ExcludeUrls To exclude extensions from the excluded URLs (using ends-with matching method) add a space separated list of tokens to the parameter ExtensionsRestriction, so that all extensions found in ExtensionsRestriction are re-included

The parameter ExcludeExtensions is a pendant to ExcludeUrls parameter and allows specific extensions to be excluded from caching, (using ends-with matching method). Extenions defined here are of higher precedence than ExcludeUrls / ExtensionsRestriction group
