HTTP Callbacks take the socket, the method and the path as arguments and should return the content, allocated with malloc(). Status should be changed to reflect the status of the request if it isn't 200 and title may be set to a malloc()'d string to an appropriate title for non-200 responses. Content length may also be specified. The return value may include additional headers at the front and MUST include a blank line with to provide separation between user headers and content (even if no content is specified). | |
