I am new to the Mediawiki API.

I would like a list of all titles that have a certain category.

This command gives me page titles with categories listed within the page.

http://localhost/wiki1_13/api.php?action=query&generator=allpages&prop=categories&gaplimit=500

I can deal with this command but I would get way more than I need.

Also, how can I avoid the limit? I want all pages. If I have to deal with limits, can I get 1-500, then 501-1000, etc.

Thanks,
