Wordpress : Url Rewrite - wordpress

Question

I am trying to rewrite a url in wordpress so that I can serve up dynamic content based on variables that are passed. I have a plug in that needs variable data passed into it. Currently I have:
http://xyzsite.com/page/?var1=something
this works fine and passes in a $_GET var. So my next step is to clean up the variable so that it looks like
http://xyzsite.com/page/something
I have done a few google searches and come accross some site that looked promising but I cannot get any of them to work. From what I have read, i need to use
add_rewrite_tag and add_rewrite_rule
After reading through the articles I have added this to my functions.php page:
add_rewrite_tag('%var1%','([^&]+)');
add_rewrite_rule('^page/([^&]+)/?','index.php?p=1141&var1=$matches[1]','top');
when i navigate to the page http://xyzsite.com/page/something i get a 404 error. When i navigate the to http://xyzsite.com/page/?var1=something it is still working fine. So it looks as if my rewrite is not registering or working correctly.
Can someone help me to achieve the above rewrite. FYI my permalink settings is set to post name if that matters at all. Thank you.

The stroked out text above is wrong, as Gustavo Straube pointed out in the comments. Please disregard that proposed solution.
My only last advice is to try adding a flush_rules(); after your last add_rewrite_rule, as stated in http://codex.wordpress.org/Rewrite_API/flush_rules.
Note that you should be accessing your query vars with get_query_var('var_name') instead of trying to access $_GET directly.
