Because, as Lucas has stated below, the '+' character only translates to ' ' when it is part of the query-string. The only valid way to get a ' ' encoded before the query-string is to use %20. Which is why you should save a lot of hair-pulling, and only allow filenames without spaces :). > > Lucas Galfaso wrote: >> >> Short answer: >> An URL has many part, one part that is called "path" (in this case >> "upload/a b.jpg") and another part is called "query" (that is usually >> what is after the "?" in a URL) These two parts use slightly different >> reserved characters that may, should, or must be escaped under >> different rules.
