small patch for Net_URL

I would like to submit this small patch to Net_URL. The problem is that Net_URL checks HTTP_SERVER_VARS['HTTPS'], which may or may not exist, and if the key 'HTTP' doesn't exist, it throws an error. It is prefixed with a '@' to prevent error spam, but this doesn't help if you're using your own error reporting function. I don't think PEAR classes should throw any errors that arn't 'real' errors. Anyway, this small patch avoids the error if HTTP_SERVER_VARS['HTTPS'] doesn't exist. thanks, baba -- Baba Z Buehler <baba@BabaZ.com> http://BabaZ.com/ PGP KeyID: 0xA88A6D4C "Those who are willing to sacrifice freedom for security deserve neither." -Benjamin Franklin
