I have a system based on Zend, and I've moved it from Apache to nginx.
But I experience a strange parameter issue on some of my links.

It is basically a calendar, and the link will point to "tomorrow"

This is how one of my links appear when running on Apache:
http://www.myserver.com/sp/bs/si/9/sp/244/e/52/month/09/year/2012/day/23

But when running on nginx, the link looks like this:
http://www.myserver.com/sp/bs/si/9/sp/244/q//sp/bs/si/9/sp/244/year/2012/month/09/day/22/month/09/year/2012/day/23

So it adds "/q//" and also messing up other parts of the link.

Have anyone else experienced something similar?
I'm not sure if I've given enough information, pls let me know if you need more details.

Thank you,
