The handler generates a response containing a simple HTML form. * The POST handler expects the form values to be in the body of the HTTP request and percent-encoded. Fortunately, GCDWebServer provides the request class 'GCDWebServerURLEncodedFormRequest' which can automatically parse such bodies. The handler simply echoes back the value from the user submitted form. ```objectivec [webServer addHandlerForMethod:@"GET" path:@"/" requestClass:[GCDWebServerRequest class] processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) { NSString* html = @" \ \ \ \ "; return [GCDWebServerDataResponse responseWithHTML:html]; }]; [webServer addHandlerForMethod:@"POST" path:@"/" requestClass:[GCDWebServerURLEncodedFormRequest class] processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) { NSString* value = [[(GCDWebServerURLEncodedFormRequest*)request arguments] objectForKey:@"value"]; NSString* html = [NSString stringWithFormat:@"%@
", value]; return [GCDWebServerDataResponse responseWithHTML:html]; }]; ```
