I am having a perplexing problem trying to retrieve a list of querypage results. The problem is that when I access the API from a script, I can only retrieve 1000 results from the API, while if I use exactly the same query manually in a browser, I can retrieve up to 5000 results. Here is an example of the query:

http://simple.wikipedia.org/w/api.php?action=query&list=querypage&qp...

When I put this query into Firefox manually, it returns the expected 100 results, plus a "query-continue" key. However, when I run exactly the same query from a Python script, it returns the same 100 results, but no "query-continue". (When qpoffset is less than 900, the script *does* return the "query-continue" key, the problem only occurs when trying to go past offset 1000.)

The _only_ difference I can identify between the two queries is that the browser is doing an HTTP GET, while the Python script is doing an HTTP POST. Everything else is identical, which I have verified by logging the queries sent and responses received by the script and comparing them to my manual queries.

Should GET vs. POST make a difference in the results returned by list=querypage? I've never seen this happen on any other type of API query.

If that's not it, is there any other possible explanation?
