I'm trying to do a simple redirect but for some reason it never works. I need this:

/dir/script1.php?t-80893.html -> /script2.php?t=80893

and tried:

rewrite ^/dir/script1\.php\?t-(.*)\.html$ /script2.php?t=$1 last;

but I just get a 404 error. I tried different options but it never works. It's like the ? breaks the whole rewrite rule. Any idea how I can make a redirect like this work?
