htaccess rewrite??

Hey gang!
Not sure if anyone can help me with this...

I'm trying to learn some htaccess rewrites and I'm not figuring it out.

For my test I have two html pages, TEST.HTML and TEST2.HTML

TEST.HTML has a link to go to TEST2.HTML:

the link is test2.html?var1=a&var2=b

I'm trying to rewrite the URL to:

test2.html/a/b

Can anyone give me some pointers on where to start? I've tried numerous different things, but it's not working.

Please let me know if you need any further info.

Thanks so much!!!!
