1. I don't want to modify ever script I have with the ob_start function call.
2. I looks like my expires and gzip modules aren't enabled.

1. If you have a common script that you include in every page, you can (and should) use that to set the ob_start. If not, you still can include .php extension in the .htaccess code I mentioned above.

2. I'm afraid you will need to get those modules installed/enabled for this to work.
