Method Detail

handle

public void handle(Request req,
                   Response rsp,
                   Route.Chain chain)
            throws Throwable

Description copied from interface: Route.Filter

The handle method of the Filter is called by the server each time a request/response pair is passed through the chain due to a client request for a resource at the end of the chain. The Route.Chain passed in to this method allows the Filter to pass on the request and response to the next entity in the chain.

A typical implementation of this method would follow the following pattern:

• Examine the request
• Optionally wrap the request object with a custom implementation to filter content or headers for input filtering
• Optionally wrap the response object with a custom implementation to filter content or headers for output filtering
• • Either invoke the next entity in the chain using the Route.Chain object (chain.next(req, rsp)),
  • or not pass on the request/response pair to the next entity in the filter chain to block the request processing
• Directly set headers on the response after invocation of the next entity in the filter chain.

Specified by:

handle in interface Route.Filter

Parameters:

req - A HTTP request.

rsp - A HTTP response.

chain - A route chain.

Throws:

Throwable - If something goes wrong.
