WMS_CACHE_QUERY_MISS_RESPONSE

The WMS_CACHE_QUERY_MISS_RESPONSE enumeration type indicates what action the server must take in response to a cache miss.

typedef enum WMS_CACHE_QUERY_MISS_RESPONSE{
  WMS_CACHE_QUERY_MISS_SKIP = 0,
  WMS_CACHE_QUERY_MISS_DISCONNECT = 1,
  WMS_CACHE_QUERY_MISS_REDIRECT = 2,
  WMS_CACHE_QUERY_MISS_REDIRECT_TO_PROXY = 3,
  WMS_CACHE_QUERY_MISS_PLAY_BROADCAST = 4,
  WMS_CACHE_QUERY_MISS_PLAY_ON_DEMAND = 5,
  WMS_CACHE_QUERY_MISS_FORWARD_REQUEST = 6,
  WMS_CACHE_QUERY_MISS_PROCESS_REQUEST = 7
};

Members

WMS_CACHE_QUERY_MISS_SKIP	The plug-in will not service this request.
WMS_CACHE_QUERY_MISS_DISCONNECT	Disconnect the client.
WMS_CACHE_QUERY_MISS_REDIRECT	Redirect request to another server.
WMS_CACHE_QUERY_MISS_REDIRECT_TO_PROXY	Redirect the client to another cache proxy.
WMS_CACHE_QUERY_MISS_PLAY_BROADCAST	Play the request as a broadcast stream.
WMS_CACHE_QUERY_MISS_PLAY_ON_DEMAND	Play the request as an on-demand stream through the cache proxy on-demand publishing point.
WMS_CACHE_QUERY_MISS_FORWARD_REQUEST	Forward the request to an upstream server. This response is valid only when the server calls the QueryCacheMissPolicy method on the IWMSCacheProxy interface with the lQueryType parameter equal to WMS_CACHE_QUERY_GET_CONTENT_INFO or WMS_CACHE_QUERY_CACHE_EVENT.
WMS_CACHE_QUERY_MISS_PROCESS_REQUEST	The server determines how to process the client request. This response is valid only when the server calls the QueryCacheMissPolicy method on the IWMSCacheProxy interface with the lQueryType parameter equal to WMS_CACHE_QUERY_GET_CONTENT_INFO or WMS_CACHE_QUERY_CACHE_EVENT. It has the following meanings:

• If the lQueryType parameter equals WMS_CACHE_QUERY_GET_CONTENT_INFO, the server uses the pContentInfo parameter passed by the plug-in when it calls the OnQueryCacheMissPolicy method on the IWMSCacheProxyCallback interface to respond to the client's request. If pContentInfo is null, the server uses the bstrOriginUrl parameter instead.

• If the lQueryType parameter equals WMS_CACHE_QUERY_CACHE_EVENT, the server raises the associated event locally rather than propagating it to the origin server.

Remarks

You can use this enumeration in a cache plug-in when you implement the QueryCacheMissPolicy method on the IWMSCacheProxy interface or the OnGetContentInformation method on the IWMSCacheProxyServerCallback interface.

Requirements

Header: streamcache.h.

Library: WMSServerTypeLib.dll.
