Method Detail

lookupPolicy

public static CachePolicy lookupPolicy(javax.servlet.ServletConfig config,
                                       javax.servlet.http.HttpServletRequest request,
                                       java.lang.String policyFile)
                                throws CachePolicyLoadingException

A method to lookup and construct a cache policy object from a cache policy file

If the cache policy is already loaded previously either in ocs4j or your own servlet context (depends on your cache_policy_in_ocs configuration), then it will just reuse the existing cache policy object in memory, instead of reloading and re-parsing the cache policy file. The first loading will store the cache policy object in memory for later reuse.

Parameters:

config - user's current ServletConfig object

request - user's current HttpServletRequest object

policyFile - a string that specifies the URI to the cache policy file; the URI path is relative to your servlet context;

Returns:

the loaded cache policy object

Throws:

CachePolicyLoadingException

refreshPolicy

public static CachePolicy refreshPolicy(javax.servlet.ServletConfig config,
                                        javax.servlet.http.HttpServletRequest request,
                                        java.lang.String policyFile)
                                 throws CachePolicyLoadingException

A method to reload, re-parse and re-construct a cache policy object from a cache policy file

No matter whether the cache policy is already loaded previously. This method will always reload, re-parse and re-construct the cache policy object from the cache policy file. After reloading, this method will store the cache policy object in memory for later reuse.

Parameters:

config - user's current ServletConfig object

request - user's current HttpServletRequest object

policyFile - a string that specifies the URI to the cache policy file; the URI path is relative to your servlet context;

Returns:

the loaded cache policy object

Throws:

CachePolicyLoadingException
