Nginx rewrite rule results in a 404 (Sometimes)

view story

http://serverfault.com – We use a product called VBseo for our vBulletin powered forums. VBSEO comes with nginx rewrite rules in the package, but we cannot get them to work properly and their support hasn't been all that helpful so far. The purpose of VBSEO is to change vBulletin's default URLs into search engine friendly, keyword-rich URLs. One script (vbseo.php) handles ALL of the rewritten forum URLs. On stock vBulletin, the URLs look like this: /forumdisplay.php?f=1 /showthread.php?t=12345 /member.php?u=12345 With VBSEO installed, those URLs look like this: /forum-name /forum-name/thread-name.html /members/ (HowTos)
