Fortunately the HTTP protocol provides two main ways to send information to a web server above and beyond the URL of a requested file.
These two ways are the POST and GET methods.
HTTP/1.0 also specifies a HEAD method that is used to transmit header information only. It is used primarily by indexing search robots and not web programmers so we will not discuss it here. Similarly we will not discuss the PUT or the DELETE methods that are a part of the HTTP 1.1 specifications still in formulation.
