Title: Clarify requirement to use CONTENT_TYPE and CONTENT_LENGTH

Shouldn't CONTENT_TYPE and CONTENT_LENGTH be added to the list of required-if-not-empty variables? HTTP 1.1 states these headers SHOULD be used if possible.

Also, I've clarified that HTTP_CONTENT_TYPE and HTTP_CONTENT_LENGTH should not be used.
