Since I tend to forget what bits and pieces are needed for TIdHTTPWebBrokerBridge, the below code piece from:
The [WayBack] WebReq.WebRequestHandler Function returns a reference to the global [WayBack] TWebRequestHandler object. This object manages all the Web modules in the application, and creates Web request and response objects when the application receives HTTP request messages: TWebRequestHandler keeps a pool of active Web modules. In response to a request from the application, TWebRequestHandler creates a request object and assigns it to one of the active Web modules.
The code below is the Indy counterpart of hooking up a classic WebSnap WebBroker (you could also hook the Web.WebBroker.Application.WebModuleClass to TMyWebModule instead of the WebRequestHandler.WebModuleClass, as Web.WebBroker.Application.WebModuleClass is a TWebApplication which inherits from TWebRequestHandler).
