Assets browser
Matched /assets/{*path:nonfile} - a catch-all with a constraint.
- path
- (empty - the catch-all matched zero segments)
Constraints on catch-alls
The constraint sees the whole remainder ("img/logo", slashes and all) and the bound
value always stays a string - typed conversion deliberately skips catch-alls, mirroring the
built-in router. nonfile checks only the text after the last slash, so directory
paths pass while app.js is rejected. On the empty remainder
(/assets itself) the constraint sees a missing value: nonfile
accepts that, any other constraint would not ({*path:int} wouldn't match
/assets).
@* /assets → path = "" (missing value: nonfile accepts) /assets/img/logo → path = "img/logo" ("logo" is not a file name) /assets/app.js → no match ("app.js" IS a file name) *@ <Broute Path="/assets/{*path:nonfile}" Component="@typeof(AssetsPage)" />
