stopping a 'silent' redirect with php/fcgi

[Jonathan Vanasco]

This has been killing me, trying to figure out what was going on:

		http://www.domain.com/Path/To?a=123

Is always redirected (302) to

		http://www.domain.com/Path/To/

But

		http://www.domain.com/Path/To/?a=123

works fine.

can anyone offer me a suggestion as to where i can keep this from  
happening ?

This seems to happen within nginx itself -- however i can't find any  
settting that would cause this.
