PHP as web proxy ?

[Bogdan Zamfir]

Hi,

I need to use a PHP app as a sort of a web proxy
To be more specific:

I have a mailserver with own web server and web interface. What want it to
be able to dynamically change its output pages (but I cannot interface
directly PHP with its web browser)

So, suppose the web mail server runs on

http://www.webserver.com

and I have my site at

http://www.myphpserver.com

What I need is user to connect to
http://www.myphpserver.com/webserver/index.htm, and when my PHP webserver
receive this request, it will request the page from
http://www.webserver.com/index.htm. Then it will make some processing on the
returned HTML page (like changing CSS, adding banners, rewrite form's Action
parameter, etc), and will return this page to client.

When client will post a page (like clicking on a submit button), my php page
will receive it, and pass it to original action URL together with all
POST-ed data

Any thoughts how t do this?

Thanks,
Bogdan

err... something like:

$replace=array( 'GET');
$with=array('PO ST');

foreach($_POST as $name=>$val) {
$params.=$name . '=' . urlencode($val) . '&';
}
$params=substri ng($params,0,-1);
$in=file_get_co ntents("http://www.webserver.c om/index.htm?$para ms");
$out=preg_repla ce($replace,$wi th,$in);
print $out;

If you want to POST to the back-end, you'll need a lot more code.

Actually, similarly to this I am behind a firewall here at work.... :$

I have idly wondered whether something like this could be put together to
stop the firewall banning certain domains (like my webmail), and possibly
even allowing data to be forwarded through to another protocal? For example,
connecting to an IMAP server where the IMAP ports are blocked on the
firewall?

Any ideas?
