Default Cache Configuration

If you enable caching but do not provide any special configuration for a servlet or JSP, the default cache configuration is as follows:

• The default cache timeout is 30 seconds.

• Only the HTTP GET method is eligible for caching.

• HTTP requests with cookies or sessions automatically disable caching.

• No special consideration is given to Pragma:, Cache-control:, or Vary: headers.

• The default key consists of the Servlet Path (minus pathInfo and the query string).

• A "least recently used" list is maintained to evict cache entries if the maximum cache size is exceeded.

• Key generation concatenates the servlet path with key field values, if any are specified.
