If I remember well, the + sign is an old style of printing a space and this style was used in web pages that use isindex forms.

The usage of + as an encoding for space is a not explicitly documented in any RFCs, but is in common use for representing a space *in the query component of URIs*. I'm not sure if web servers will handle it correctly in the path or filename component. Therefore, I'd say that uri_encode is correct. I don't believe there's a way to get the uri_encode function to do that for you, but you can translate before or substitute after if you really need them to match. -- Matt Howard <[EMAIL PROTECTED]> -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response> -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
