I'm attempting to use curl inside php to grab a page from my own web server. The page is pretty simple, just has some plain text output. However, it returns 'null'. I can successfully retrieve other pages on other domains and on my own server with it. I can see it in the browser just fine, and I can grab it with command line wget just fine, it's just that when I try to grab that one particular page with curl, it simply comes up null. We can't use file_get_contents because our host has it disabled.
Why in the world would this be different behavior be happening?
