The [WebServerRequest] class represents one incoming HTTP request. It also contains the proper helper methods for sending a response. The [WebServerRequest] class represents one incoming HTTP request. It also contains the proper helper methods for sending a response. Since HTML documents has a relatively fixed structure, this class contains head, body, footer properties, the response HTML can be added to these, and then these can be compiled and sent using [code]compile_body()[/code] or the [code]compile_and_send_body()[/code] helpers into the [code]compiled_body[/code] property. This adds an html5 type declaration then the opening [code]html[/code] tag, then the contents of the head variable to the [code]head[/code] section of the response, and then the contents of the body then footer variable into the [code]body[/code] section of the response, then it closes the main [code]html[/code] tag. It also contains helper methods for sending files, handling cookies, storing sessions, storing custom data etc. CSRF tokens are also supported. These are generated string tokens that are stored in HTTPSessions, but since they are universally needed, helper methods were added directly into [WebServerRequest]. They can be used to validate that a form was actually submitted by the user from a page rendered by the application's server itself, in order to mitigate attacks that use the technique called [C]ross [S]ite [R]equest [F]orgery. This framework uses a stack like url routing model, where the http path is split along forward slashes, and then these get handled going deeper into the given [WebServer]'s [WebNode] hierarchy, effectively using the node structure as a pseudo filesystem. Of course [WebNode]s can decide on handling the request's parameters themselves instead of letting the default hierarchy based routing to take place. For example [BrowsableFolderServeWebPage] uses this to implement a web based file browser. The currently handled segment can be queried using the [code]get_current_path_segment()[/code]. The [code]pop_path()[/code] and [code]push_path()[/code] helper methods can be used to switch segments.
