| Method Summary | |
| final protected void | applyCacheSeconds(HttpServletResponse response, int seconds)
Apply the given cache seconds and generate corresponding HTTP headers,
i.e. | | final protected void | applyCacheSeconds(HttpServletResponse response, int seconds, boolean mustRevalidate)
Apply the given cache seconds and generate respective HTTP headers.

| WebContentGenerator | | public WebContentGenerator()(Code) | | |
| applyCacheSeconds | | final protected void applyCacheSeconds(HttpServletResponse response, int seconds)(Code) | | Apply the given cache seconds and generate corresponding HTTP headers,
i.e. allow caching for the given number of seconds in case of a positive
value, prevent caching if given a 0 value, do nothing else.
Does not tell the browser to revalidate the resource.
Parameters:
response - current HTTP response
Parameters:
seconds - positive number of seconds into the future that theresponse should be cacheable for, 0 to prevent caching
See Also: WebContentGenerator.cacheForSeconds(javax.servlet.http.HttpServletResponse,int,boolean) |
| applyCacheSeconds | | final protected void applyCacheSeconds(HttpServletResponse response, int seconds, boolean mustRevalidate)(Code) | | Apply the given cache seconds and generate respective HTTP headers.
That is, allow caching for the given number of seconds in the
case of a positive value, prevent caching if given a 0 value, else
do nothing (i.e. leave caching to the client).
Parameters:
response - the current HTTP response
Parameters:
seconds - the (positive) number of seconds into the future thatthe response should be cacheable for; 0 to prevent caching; anda negative value to leave caching to the client.
Parameters:
mustRevalidate - whether the client should revalidate the resource(typically only necessary for controllers with last-modified support) |
| cacheForSeconds | | final protected void cacheForSeconds(HttpServletResponse response, int seconds, boolean mustRevalidate)(Code) | | Set HTTP headers to allow caching for the given number of seconds.
Tells the browser to revalidate the resource if mustRevalidate is
true.
Parameters:
response - the current HTTP response
Parameters:
seconds - number of seconds into the future that the responseshould be cacheable for
Parameters:
mustRevalidate - whether the client should revalidate the resource(typically only necessary for controllers with last-modified support) |
| checkAndPrepare | | final protected void checkAndPrepare(HttpServletRequest request, HttpServletResponse response, boolean lastModified) throws ServletException(Code) | | Check and prepare the given request and response according to the settings
of this generator. Checks for supported methods and a required session,
and applies the number of cache seconds specified for this generator.
Parameters:
request - current HTTP request
Parameters:
response - current HTTP response
Parameters:
lastModified - if the mapped handler provides Last-Modified support
throws:
ServletException - if the request cannot be handled because a check failed |
| checkAndPrepare | | final protected void checkAndPrepare(HttpServletRequest request, HttpServletResponse response, int cacheSeconds, boolean lastModified) throws ServletException(Code) | | Check and prepare the given request and response according to the settings
of this generator. Checks for supported methods and a required session,
and applies the given number of cache seconds.
Parameters:
request - current HTTP request
Parameters:
response - current HTTP response
Parameters:
cacheSeconds - positive number of seconds into the future that theresponse should be cacheable for, 0 to prevent caching
Parameters:
lastModified - if the mapped handler provides Last-Modified support
throws:
ServletException - if the request cannot be handled because a check failed |
| getCacheSeconds | | final public int getCacheSeconds()(Code) | | Return the number of seconds that content is cached.
|
| getSupportedMethods | | final public String[] getSupportedMethods()(Code) | | Return the HTTP methods that this content generator supports.
|
| isRequireSession | | final public boolean isRequireSession()(Code) | | Return whether a session is required to handle requests.
|
| isUseCacheControlHeader | | final public boolean isUseCacheControlHeader()(Code) | | Return whether the HTTP 1.1 cache-control header is used.
|
| isUseExpiresHeader | | final public boolean isUseExpiresHeader()(Code) | | Return whether the HTTP 1.0 expires header is used.
|
| preventCaching | | final protected void preventCaching(HttpServletResponse response)(Code) | | Prevent the response from being cached.
See www.mnot.net.cache docs.
|
| setCacheSeconds | | final public void setCacheSeconds(int seconds)(Code) | | Cache content for the given number of seconds. Default is -1,
indicating no generation of cache-related headers.
Only if this is set to 0 (no cache) or a positive value (cache for
this many seconds) will this class generate cache headers.
The headers can be overwritten by subclasses, before content is generated.
|
| setRequireSession | | final public void setRequireSession(boolean requireSession)(Code) | | Set whether a session should be required to handle requests.
|
| setSupportedMethods | | final public void setSupportedMethods(String[] methods)(Code) | | Set the HTTP methods that this content generator should support.
Default is HEAD, GET and POST.
|
| setUseCacheControlHeader | | final public void setUseCacheControlHeader(boolean useCacheControlHeader)(Code) | | Set whether to use the HTTP 1.1 cache-control header. Default is "true".
Note: Cache headers will only get applied if caching is enabled
for the current request.
|
| setUseExpiresHeader | | final public void setUseExpiresHeader(boolean useExpiresHeader)(Code) | | Set whether to use the HTTP 1.0 expires header. Default is "true".
Note: Cache headers will only get applied if caching is enabled
for the current request.
