I couldn't get rewrites working with site.com/user/account unless I appended a file extension
Uh-oh, there's something wrong here. Are there any other rules you haven't told us about?
The rules in the original post require the .php in the URL request.
The OP is merely asking how to modify those rules.
Urk! Isn't there a question about that, just a few posts further down this forum? If you do have a slash, does something break outright or are you just left with an unhappy php page plotting revenge?
Beware that unescaped slashes are NOT a valid character within query string parameters. That may cause you some trouble.
While not valid, they do work on some systems. It's not something to rely on though.
I usually block any and all requests with http or slashes, and a number of other things, in any query string as those are things that hackers may use.
