Class ClientCachingFilter

  • All Implemented Interfaces:
    javax.servlet.Filter
    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
