Is the following URL valid?

http://www.example.com/module.php/lib/lib.php

According to https://www.rfc-editor.org/rfc/rfc1738 section the hpath element of an URL can not contain a ‘.’ (period). There is in the above case a ‘.’ after "module" which is not allowed according to RFC1738.

Am I reading the RFC wrong or is this RFC succeed by another RFC? Some other RFC’s allows ‘.’ in URLs (https://www.rfc-editor.org/rfc/rfc1808).

    I don’t see where RFC1738 disallows periods (.) in URLs. Here are some excerpts from there:

    hpath          = hsegment *[ "/" hsegment ]
hsegment       = *[ uchar | ";" | ":" | "@" | "&" | "=" ]
uchar          = unreserved | escape
unreserved     = alpha | digit | safe | extra
safe           = "$" | "-" | "_" | "." | "+"

    So the answer to your question is: Yes, http://www.example.com/module.php/lib/lib.php is a valid URL.
