I wrote a program to java that reads a website, and downloads some files.

When you click on download.php?id=id does some work and then redirects you to the download file. This website had another server and recently update to nginx.

Since then my program does not work as before. I have located the error to the Location: header

It seems that it doesn't encode the urls, and replace the spaces with "%20". Firefox does this automatically but java doesn't.
I don't know if this is considered as a bug, i am just mentioning it. The fix is 2 lines of code. Replace all spaces with %20

I found a way around that in java, in this page http://forums.sun.com/thread.jspa?threadID=5170856 where you can read about the "problem"

Thank you Nikos Glikis
