URLs and percent encoding
Read OriginalThe article details a developer's realization that automatically decoding percent-encoded URLs in a library (libdav) is flawed. Using examples like '/path/to/theitem%2Fwithslash.ics', it explains how decoding reserved characters like '/' changes the resource's meaning. It references RFC3986 to distinguish between reserved and unreserved characters and advises treating URL paths as opaque strings for safety, with normalization only for comparison.
