Implement the X-Forwarded-For header

[harry2cool]

We use Google Page Speed Service to speed up our website.

Can one please suggest how to implement the X-Forwarded-For header on the website, both catlog and admin side.

We have done this on server level, but still finding issues.

Thanks

What specific problem are you encountering?
What ZC version are you using?

After enabling Google PSS for some pages we get the below message
"
"Fetching of original content failed with the following error: Proxy Publisher Failure - NO RESPONSE. If you own this domain, please consult this FAQ."
"

The link to the above FAQ is: http://code.google.com/speed/pss/faq...blisherfailure

We were also told:

=============

We suspect that some of the requests from PSS are not handled correctly by your origin servers because they are seeing a large number of requests coming from a small set of IP addresses (Google's PSS servers).

To fix this situation, we recommend configuring your origin server to read the IP address of the user from the "X-Forwarded-For" HTTP header, rather than the default set up. You can read more about implementing the X-Forwarded-For header at https://developers.google.com/speed/...s/faq#clientip

===========

We have setup the X-Forwarded_For at server level, still we face this issue hence we were told to test at script level

Thanks

Zen Cart already uses x_forwarded_for, if it's available:

function zen_get_ip_address() {
  if (isset($_SERVER)) {
    if (isset($_SERVER['HTTP_X_FORWARDED_FOR'])) {
      $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
...

Thanks Dr Byte, nice to know it already exists and for your wonderful help.

By "if it's available:" , do you mean if a proxy feature is being used, Zencart automatically passes the actual Ip's

[DrByte]

By "if it's available", I mean: if the webserver software (ie: Apache, etc) is passing the $_SERVER variable to PHP, and that $_SERVER array contains the HTTP_X_FORWARDED_FOR element, it will assume that your apache server is passing the real IP via that variable, and then Zen Cart will use that for the IP address instead of the usual REMOTE_ADDR value.
It's all dependent on your webserver being correctly configured with your proxy server ... so it's up to your network administrator to properly configure your proxy server and your apache webserver.

Thanks Dr Byte, this clarifies all.
Made a script which proves we are passing the real IP on the server ,
Zen Cart already uses x_forwarded_for, it's available at our server.
Will pass it to the Google guys .
PSS is still in beta probably the reason for the issues.
