I'm new to the rewrite module in Apache. So far, I have sucessfully set up it to work like this.
For 1 pair of parameter name and value:
RewriteRule ^/([^/]+)/([^/]+)/?$ /list.jsp?$1=$2
For 2 pairs of parameters, I would do something like this:
RewriteRule ^/([^/]+)/([^/]+)/([^/]+)/
Now, the problem is that the number of parameters for list.jsp can be more than 2 (say 3,4,5, or 10).
What's the best solution to handle this?
Do I need to define each rule of each number of parameters? Is there any better way?

Well, I thought a pattern like this might work:
^([^/]+/){0,8}([^/]+/?)$
(I'm using .htaccess, so my slashes may be on the opposite side to yours).
Unfortunately, the variable-occurrence term (marked by {0,8} allowing zero to eight occurrences), only seems to capture the final matching occurrence. So a request for:
http://127.0.0.1/one/two/t
was only returning $1 as four/ and $2 as five/ which is obviously of no use. I don't know of any way to alter this behaviour from the pattern matcher.
So I recommend just capturing the lot, and then using a Java method to split the captured string by forward slashes. PHP has a function called explode, but I'm not sure what Java's equivalent might be. It will mean a bit more effort.
The alternative is to write out a rule for each possibility. Not a pretty solution, but that ought to work too.
