php server variables
x-requested-with missing in php $_SERVER variable when using apache?
hi, i'm having a problem. i'm requesting some content from the apache server using ajax. in php, i want to detect if the request was done through ajax and i know the way to detect this is to see if x-request-with is in the $_SERVER variable. i checked HTTP_X_REQUEST_WITH but it's missing.
i don't know but what are possible causes why this may be lost? if this will help, i'm using an alias to access my pages.
thanks!
AFAIR $_SERVER scope vars (in most CGI languages, I am NOT very proficient in PHP) hold global server info, request is NOT global, it is short lived and very specific.
I suggest you try looking in CGI scope instead...
