#2 cPanel 11 bug fix

[Andre Messerschmidt]

cPanel 11 uses the Location HTTP header field for page redirection. This means that redirections to URI's containing "webmail" are not escaped, which means that the standard server redirection bypasses the proxy.

To fix this, parse the HTTP header filelds and escape "webmail"

Where the HTTP response headers are parsed, add the following:
// Fix redirect location URL
if (strpos($data, 'Location: ') === 0)
{
$data = str_replace('/webmail', '/webmail_', $data);
}

This will now parse the Location field and cPanel proxy will work for webmail with cPanel 11.

The loop to process the response header should now be:
while (true) {
$data = fgets($server, 10240); // FIXME: Can we optimize here with another buffer-size?
if (strlen(trim($data))==0) break;

// Fix hostname in redirects, cookies...
$data = str_replace(
array('localhost:2095', 'localhost:2082', 'localhost:2086'),
array($webmailhost, $cpanelhost, $whmhost),
$data);
if (substr($data, 0, 11) == 'Set-Cookie:') {
$data = str_replace(
'; domain=localhost',
'; domain='.$_SERVER['HTTP_HOST'],
$data);
}

// Fix redirect location URL
if (strpos($data, 'Location: ') === 0)
{
$data = str_replace('/webmail', '/webmail_', $data);
}

header($data, false);
}

After composing a message in Squirrelmail and pressing send it gives me a page cannot be displayed and is referencing webmail_.domain.com instead of webmail.domain.com.

It also does the same thing if you just try to open Horde, or purge your deleted items in Squirrelmail. I'm sure there are other things.

Can this be resolved? The script works great otherwise.
