Could you record the tests you perform with jmeter, and then run the tests against the sites in the future?

I've heard selenium is good for functional testing, I've always used jmeter though.

That is exactly what we're doing. I used Selenium to create all the tests. We have 10-15 websites that we build on the same framework, so in many cases, one test is applicable to every site.
