Re: [users@httpd] File upload to Apache server without third party software
Well, It's very possible you know something I don't, but based on my
understanding on POST, it sounds like you're confused about how it
works. The use case I'm familiar with is to create a cgi script, or a
server side script like PHP that receives the POST data and saves it
to a file. And you're right, it is just like GET, the content of the
URL you specified will be returned by the server. The only difference
I know of between GET and POST is that with GET, the client sends data
encoded in the URL, and with POST, the data is included as the body of
the HTTP request.. That's why post is used for uploading files.
However---and again, this is just my understanding of it---POST is not
intended to just arbitrarily create or change files on the server, you
have to use some server side mechanism (again, a cgi or php or
something) to actually receive the POSTed data and write it to a file.
It sounds like what you may be interested in is some sort of WebDAV
method. This is an extension to the HTTP standard that's meant for
sharing files over an HTTP connection, and it has more powerful
methods than standard HTTP. I'm not sure if it has something you're
looking for, but it might be worth a look.
Hope that helps,
-Brian

Thanks Brian, I agree with what you wrote.
Prasanth, maybe the correct place to start is here :
http://www.faqs.org/rfcs/rfc2616.html
The various HTTP "methods" are described in section 9.2 and later.
I suggest to start reading from the beginning however.
The way in which Apache and some of its modules work (or any other web
server for that matter), are only understandable when you have at least
a basic understanding of the HTTP protocol.
By telling you that, we are trying to help you. The questions you are
asking, and the way you are asking them, makes us think that you are
missing some basic parts of the puzzle.
For example, Brian mentioned WebDav.
You will find how to set it up in Apache here :
http://httpd.apache.org/docs/2.2/mod/mod_dav.html#dav
Installing Dav in Apache will allow you to send PUT requests, including
a file to upload to your server. It will do that right out-of-the-box,
which is what you seem to want.
But, do you notice the red box in the middle of the page ?
It tells you that unless you know exactly what you are doing, anybody
having access to your webserver is going to be able to download any file
from your computer, or upload any file to it. For example, /etc/passwd.
It is much like making the C:\ directory of your PC into a network
share, with read/write permission to Everyone.
I am quite sure you do not want that.
