Pagination, filtering results and Get variables

[eluser]gh0st[/eluser]
I have a paginated list of items (ie: people who reside in a country) which my client requires filters for the country name.

However, GET is switched off and it is very hard to switch GET back on, and still keep the clean URLs.

Although there is only one filter for this page, the next page has 3 filters.

What I don't want it something like this though

someurl.com/[controller]/[method]/[page]/[s<omething]/[something]/[something] .... etc

Because what happens if the second [something] is not there?

I've tried switching the use Get on in the config and switching to PATH_INFO, but this ruins all the URLs.

I just want to do this:

someurl.com/[controller]/[method]/[page]/?filter1=&filter2;=

Is it not possible to do this?

Thanks.
