Re: OT: Where did URI pipe symbol hack originate?
>Hah! We've got people looking at that same RFC and saying colons are >reserved! Oh yes, they're reserved all right: reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | "," But "reserved" doesn't mean what you might guess: The "reserved" syntax class above refers to those characters that are allowed within a URI, but which may not be allowed within a particular component of the generic URI syntax; they are used as delimiters of the components described in Section 3. And in the path part of the URI, they don't have any syntactic meaning so they're allowed: abs_path = "/" path_segments [...] path = [ abs_path | opaque_part ] path_segments = segment *( "/" segment ) segment = *pchar *( ";" param ) param = *pchar pchar = unreserved | escaped | ":" | "@" | "&" | "=" | "+" | "$" | "," On the other hand, you'll see that the production for rel_path makes the first segment special; you can't use C:/foo as a relative URI, because it would be confused with a scheme called "C". So you might want to escape colons when generating relative URIs. -- Richard
