// As of Go 1.20 filepath.Clean has different behaviour on OS related filesystems so we need to use path.Clean
|
|
// on Windows which has some caveats. The Open methods might return different errors than earlier versions and
|
|
// as of 1.20 path checks are more strict on the provided path and considers [UNC](https://en.wikipedia.org/wiki/Path_(computing)#UNC)
|
|
// paths with missing host etc parts as invalid. Previously it would result you `fs.ErrNotExist`.
|
|
//
|
|
// For 1.20@Windows we need to treat those errors the same as `fs.ErrNotExists` so we can continue handling
|
|
// errors in the middleware/handler chain. Otherwise we might end up with status 500 instead of finding a route
|
|
// or return 404 not found.
