So I guess that all depends on what you are asking when you say is it ok to do this.
If you are asking from an F5 configuration standpoint, I agree with Aaron that if you are learning URLs tightening would be your best option using the *.
However if you are asking from a Security standpoint, my personal opinion on tightening is that I don't do in the production environment, I do 99.9% of tightening and staging (policy building) in a controlled test environment and then copy that policy to production. I have occasionally done some very targeted staging for parameters in production and I do stage new Attack Signatures, but that is about it. Unless you can control who is hitting your site during your tightening period I would restrict it to test environment only. Just my personal opinion.
