Thank you for your input! I now do the following:
1) jam readlines into an array after chomping
2) marshal the array into some funky string
3) cgi.escape the marshaled string!!
4) (I *should* compress the sucker just for good measure)
5) (if you were really anal you could invent another step here -- oo! You
could "Captain" the escaped marshalled string array)

I shall call it, "Operation String Cheese" (pinky  finger goes to evil grin)

Why am I still getting random newlines using CGI.escape? Is there a certain
maximum number of characters this module can handle?

The CGI class solves this problem for you: URL's need to be escaped as
well.
