Cannot upload files from Firefox 2.0 to Apache HTTP proxy server

--00163600d09715a8ac0480f8a8d6
Content-Type: text/plain; charset=ISO-8859-1

Hi
I have tried to upload a Microsoft Excel file to my application server from
Firefox 2.0. The HTTP request goes over SSL to Oracle Apache 2 HTTP server
which is configured to act as a proxy server before passing the request to
my application server.
Packet sniffing indicates that the file contents are being sent from the
browser, but mysteriously getting 'lost' by the time they reach the
application server. i.e. the form fields relating to the file upload are no
longer present.
Are there any diagnostics I can perform or configuration I can check for the
proxy server as to why this is happening?
File uploads work fine with Internet Explorer 6. There are some minor
differences in the way HTTP requests get encoded for the two browsers, such
as the filename or content-type.
thanks, Baljeet.

password protecting a file that has parameters

--=__Part446E8D5A.0__=
Content-Type: text/plain; charset=US-ASCII
Content-Transfer-Encoding: quoted-printable

We are running apache 2.2.6 on a Linux maxchine.

We have the following code in our httpd.conf file
<Directory /usr/local/indico/MaKaC>
<FilesMatch "confRegistrationFormDisplay.py">
AuthUserFile /WWW/httpd/conf/.htpasswd
AuthName "HP2010 Web Site"
AuthType Basic
<Limit GET>
require user organizer
</Limit>
</FilesMatch>
</Directory >

Every time someone goes to http://www1.weizmann.ac.il/MaKaC/confRegistratio=
nFormDisplay.py the person is indeed asked for a user name and password. =
However, http://www1.weizmann.ac.il/MaKaC/confRegistrationFormDisplay .py =
really takes parameters e.g.
http://www1.weizmann.ac.il/MaKaC/confRegistrationFormDisplay .py?confid=3D2
and what I really want to do is require a password only for certain =
parameter values. So
http://www1.weizmann.ac.il/MaKaC/confRegistrationFormDisplay .py?confid=3D2 =
would require a user and password but
http://www1.weizmann.ac.il/MaKaC/confRegistrationFormDisplay .py?confid=3D3w=
ould not require a user and password.
When I tried adding ?confid=3D3 to the <FilesMatch> directive, it did not =
work.
Is there any way to do this?

thanks for any information.

There's no solution with FilesMatch or LocationMatch. But a possible
solution would be using mod_setenvif. I doubt if query string checking is
there with mod_setenvif. If its there, you could set an env variable and
depending on that configure auth.

You have sniffed the network both before and after the proxy right?
Have you looked for anything in your error files?

This should not be happening however...

This could ofcourse be a case of your application server not being
http/html complient. As Internet Explorer is less picky that could
explain things.

What happens if you do the test directly to the application server,
bypassing the proxy?

Re: Cannot upload files from Firefox 2.0 to Apache HTTP

Hi, thanks, I'll try to answer the questions.
Yes we have sniffed before and after the proxy. We can't exactly determine
if it reaches the proxy as it is over SSL and thus encrypted but using e.g.
HTTP Debugger shows me it is leaving the browser.
We can upload the file directly to the application server (not over SSL).
I haven't seen anything in the error logs. One thing I need to check is
whether it is a particular file type (e.g. Excel) or whether all files get
dumped if sent from Firefox.
thanks, Baljeet.
