Url rewriting problem htaccess, please help

My current url is like
http://www.mysite.info/index.php?area=1&cityname=newyork

i want it to be like
http://www.mysite.info/index.php/area/1/city/newyork/

or
http://www.mysite.info/city/newyork.html

any help appriciated.
thanks in advance.
have tried several rewriting rules from other sites.

 

What happened when you tried rules from other sites
Following rule is all you need to make it work - Provided .htaccess directives are working on your site!

RewriteRule ^city /index.php?area=1&cityname=newyork

Code (markup):

 

Options +FollowSymLinks
RewriteEngine on
RewriteRule index.php/(.*)/(.*)/(.*)/(.*)/$ /index.php?$1=$2&$3=$4

Code (markup):

that rule will make ur urls like dis

http://www.mysite.info/index.php/area/1/city/newyork/

 

I tried both but not working well. Even i have tried the server log. I did not find any error over there too.
I think my host doesn't support htaccess.
but as i use rule to change all .php to .html it works and no other rule is working.
what do you guys thinks is going wrong with my host.
recently my site's url is
http://mysite.info/index.php?area=1

first rule i tried is:
Options +FollowSymLinks
RewriteEngine on
RewriteRule index.php/(.*)/(.*)/$ /index.php?$1=$2

but there is no change

second :
RewriteRule ^city /index.php?area=1
i am not getting the second one.

Any other help please?
