It is recommended that you install the latest PTFs to upgrade to the latest

level of the HTTP Server for i5/OS. Some of the topics documented here are

not available prior to this update.

<p>The standard way of uploading files to a Web server using HTTP is through
|
||
|
|
the use of the PUT method. HTTP Server (powered by Apache) supports the PUT
|
||
|
|
method, but requires additional setup to tell the server how to handle incoming
|
||
|
|
PUT requests. One way to accomplish this is to enable WebDAV, which is provided
|
||
|
|
with HTTP Server (powered by Apache) through the module mod_dav. Another is
|
||
|
|
to provide your own CGI program and configure it for use with HTTP Server
|
||
|
|
(powered by Apache). This article discusses both options, as well as the PUT
|
||
|
|
method in general.</p>
|
||
|
|
<p><strong>About the PUT Method</strong></p>
|
||
|
|
<p>POST and PUT are two methods in the HTTP specification that are used to
|
||
|
|
permanently change files on a Web server. While the POST method is used in
|
||
|
|
conjunction with preestablished content such as Web forms, the PUT method
|
||
|
|
involves manipulating files that do not yet exist on the server. HTTP Server
|
||
|
|
(powered by Apache) supports the POST and PUT methods in the same way -- that
|
||
|
|
is, it requires a program to tell it how to handle incoming requests.</p>
|
||
|
|
<p><strong>WebDAV</strong></p>
|
||
|
|
<p>Most users will find that the easiest way to implement the PUT method for
|
||
|
|
HTTP Server (powered by Apache) is to enable WebDAV and use a client program
|
||
|
|
that supports WebDAV (such as Microsoft Web Folders) to upload files. WebDAV
|
||
|
|
is a set of extensions to the HTTP protocol, and is included in HTTP Server
|
||
|
|
(powered by Apache) through the module mod_dav. In addition to the WebDAV
|
||
|
|
extensions, mod_dav includes a PUT handler. </p>
|
||
|
|
<p>For more information on WebDAV, including a list of all the methods included,
|
||
|
|
see <a href="rzaiewebdav.htm">WebDAV for HTTP Server (powered by Apache)</a> and <a href="rzaieconfigwebdav.htm">Set up WebDAV for HTTP Server (powered by Apache)</a>.</p>
|
||
|
|
<p><strong>CGI programs</strong></p>
|
||
|
|
<p>Alternatively, you can provide your own CGI program to handle incoming
|
||
|
|
PUT requests, and configure it for use with HTTP Server (powered by Apache).
|
||
|
|
A program that handles PUT requests operates much like a program that handles
|
||
|
|
POST requests, but must include additional code for writing (and overwriting)
|
||
|
|
files on the server.</p>
|
||
|
|
<p>Because a PUT action results in a permanent change on the server, it's
|
||
|
|
important to be aware of the security issues involved in providing your own
|
||
|
|
PUT-handling CGI program. Some of these issues include:</p>
|
||
|
|
<ul><li>Ensuring the user making the PUT request is authorized to update files
|
||
|
|
on the server</li>
|
||
|
|
<li>Making sure only Web content files are updated</li>
|
||
|
|
<li>Only updating content the user is authorized to update</li>
|
||
|
|
</ul>
|
||
|
|
<p>For a more detailed discussion on providing your own PUT-handling CGI program,
|
||
|
|
see the Apache Week article <a href="http:\\www.apacheweek.com\features\put" target="_blank">Publishing Pages with PUT</a> <img src="www.gif" alt="Link outside Information Center" />.</p>
|
||
|
|
<p>Once you have a program capable of handling PUT requests, you can configure
|
||
|
|
it for use with HTTP Server (powered by Apache) using the Script directive.
|
||
|
|
For more information on the Script directive, see <a href="rzaiemod_actions.htm">Module mod_actions</a>.</p>
