Member Function Documentation

CanHandleRequest()

bool CHTTPImageHandler::CanHandleRequest ( const HTTPRequest & request ) const

overridevirtual

Checks if the HTTP request handler can handle the given request.

Parameters

request

HTTP request to be handled

Returns

True if the given HTTP request can be handled otherwise false.

Implements IHTTPRequestHandler.

Create()

IHTTPRequestHandler * CHTTPImageHandler::Create ( const HTTPRequest & request ) const

inlineoverridevirtual

Creates a new HTTP request handler for the given request.

This call is responsible for doing some preparation work like - depending on the supported features - determining whether the requested entity supports ranges, whether it can be cached and what it's last modified date is.

Parameters

request

HTTP request to be handled

Implements IHTTPRequestHandler.

GetMaximumAgeForCaching()

int CHTTPImageHandler::GetMaximumAgeForCaching ( ) const

inlineoverridevirtual

Returns the maximum age (in seconds) for which the response can be cached.

This is only used if the response can be cached.

Reimplemented from IHTTPRequestHandler.

GetPriority()

int CHTTPImageHandler::GetPriority ( ) const

inlineoverridevirtual

Returns the priority of the HTTP request handler.

The higher the priority the more important is the HTTP request handler.

Reimplemented from IHTTPRequestHandler.
