Sending User Defined Input to a Web Server
Sending User-Defined Input to a Web Server
- As you know from the introductory piece,
"Web Programming 101", web programming is a game of getting user
input, processing that input, and returning a dynamic
response.
- Thus, the first thing that you must
learn how to do is get user input from a web browser to a
web server.
- 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 1 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. |
Notes:
- Spiders will also get whole pages, to index the content
- HTTP/1.0 is used by other software which does caching,
e.g. browsers, may use HEAD to determine if update is
needed.
- links checking software uses HEAD
