HTTP Server
The Hyper Text Transfer
Protocol is used to allow other people access to your website. That's
why the HTTP Server is also known as "Web Server". There
are a lot of options available for configuring an HTTP Server. However
here are the most important ones:
- port : This is where people must connect
to gain access to your site. The default is 80.
- root : Here you must enter the folder
that contain your site. This folder must be recognized by your
operating system. Usually it is a directory in your local file
system, but you can also used a network folder mapped in your
local system (if your operating system support this).
- default file : this is used to specify
the file that will be send if the visitor is trying to access
a folder. Think that you don't write an address like "http://www.comp.com/index.htm"
instead you just write "http://www.comp.com"
this means that you try to access the root folder. The server
must know what file to send in this case. In the example above
the default file will be "index.htm". You can
enter here multiple files separated by "," . In this
case the server will look for them in the order they were entered.
This HTTP Server
also supports scripts. You can use any scripts if you have a compiler
or interpreter for that script. You can use standard scripting languages
(like perl or php) or other nonstandard scripting languages (like
bat files or sh files). For this you must create an object called
"scripts" in your server and then add script handlers
for all the file types that should be considered scripts.
At
this moment you can use java classes as scripts provided that they
extend the "pvf.site.PVFSite" base class. At this time,
support for javax.servlet was not added, but it will be added soon,
without affecting the ability to run PVFSite classes.
The
server supports virtual hosts (i.e. multiple domain names mapping
to the same IP address). For using this you must add to a running
server an object with the name of you domain. Then you will see
that you can add to that object all the options that were available
to you server. Also you should know that all unknown requests will
be controlled by the base server.
Virtual
directories can be used to specify directories that are mapped to
other physical locations that they were expected normally or to
specify security restrictions. For example you can set a virtual
directory to be "private". This will cause the server
to send an "Error 404" message if someone is trying to
access that folder or any of its sub-folders!
