Incorrect PHP server variables when redirecting to https with irules

Hello there,

We've got a f5 redirecting http traffic to https pages. However, when checking server variables in PHP, it appears that php still thinks we are using http (even though the redirection is correctly working in the browser)

The SCRIPT_URI $_SERVER variable points to http://mysite, and the HTTPS $_SERVER variable is not set (even though I'm on a https page)

Could it be a problem with the irules ?(I do not have access to the irules, so I cannot paste them here)

Thanks David
