PROVIDE_INDEX_PAGE=true
Are set, requests containing query strings without a trailing slash were being duplicated (foo?a=b were becoming foo?a=b?a=b).
Cause
The rewrite directive will automatically append the query string unless a final trailing ? is supplied. This was causing the duplication
Fix
Added an explanatory comment and a trailing ? to the rewrite rule to prevent automatic appending of the query string as we already do it in the argument to the rewrite rule.
I chose to do this rather than depending on the default behavior of rewrite since the rule as it is expressed is more explicit. The trailing ? is mysterious and so a comment was included to clarify.
