Description

Let's say client is on /hello/world/ page and requests static-file.mp3. It is relative path, so browser sends to the server full url /hello/world/static-file.mp3. In some cases we can't set absolute path, but want to get the necessary file. This library scans every part of url to find a match. It will try to get:

• staticPath + /hello/world/static-file.mp3
• staticPath + /world/static-file.mp3
• staticPath + static-file.mp3

If any file of the specified exists, then you will get it.
