SSL > fread(fsockopen()) > Not working
When I go to https://www.thawte.com:443/ I see a secure web page there.
So why does the below command return nothing?
shell> php -r 'fwrite(fsockopen("ssl://www.thawte.com"
string(0) ""

hmm, I doubt that such a host exists :)
better use
Host: www.thawte.com\r\n

443 is the standard port for SSL

what has a standard to do with this? noone restricts you to run HTTPS on any other port.
Anyway, that's out of scope here, the FQDN does not allow to contain : (colon), and as the Host header only allows FQDNs or IPs, the given string is invalid.

ahoffmann: I believe the colon is allowed in t he HTTP header per RFC 2616 linked below.
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.23
kelvinwkw: Looks like you're on the right track. But the code returns with the below error on PHP 5.2
The code below works to read via GET over SSL but I'm stuck on getting a POST to work. But that's scope creep, I guess I'll need to post another question.

dooh, missed the optional part. Thanks for correction.
Anyway, the port part in the host header is optional, hence not part of the solution here.

kelvinwkw: Yes, that works! I'll give you points.
Your POST example wasn't via SSL. Do you have a working SSL POST example? I cannot get POST to work over SSL. Can you?

Arg. I figured it out, I was missing the below line in t he header.
Content-Type: application/x-www-form-url
And that caused the POST'ed variables to bomb out and hang everything to no end.
