Perhaps still not clear enough ... !!!???
How about this ...
After trimming, the user input string should contain no whitespace.
The string should now be split into 3 sections:
1. Scheme, eg: (http|https|ftp), followed by ://
2. A run of arbitrary case-insensitive strings separated by single
dots, and ending with a gTLD or CC, or a gTLD/CC followed by a
colon and port number, eg:
mydomain.com
www.MyDomain.net.de
www.things.morethings.mydomain.info
search.mydomain.org:80
3. Begins with a forward slash, followed by nothing or almost anything
The third section could be a path to a directory or file, eg:
/
/index.html
/stuff/
/stuff/page.html
followed by a question mark ? and a query/parameter string, eg:
/stuff/?id=this&q=that
/?id=this;q=that
function parse_url http://uk.php.net/manual/en/function.parse-url.php
will break a string into 8 possible components:
scheme, host, port, user, pass, path, query, fragment
For our purposes, we might want to reject anything that contained
user, password or fragment -- but our main requirement is that the
individual components and the string as a whole should formally be a
valid URL.
We don't want to correct the users' input, for example by url-encoding
non-alphanumeric characters in a query section -- we want to tell them
that their input is not a valid URL, and ask them to correct it.
Here are some examples of error input we want to catch ...
htp://www.mydomain.com
http//www.mydomain.com
www.mydomain.com
http://www . mydomain. com
http://www,mydomain.com
http://www.mydomain
http://www.mydomain.com.index.html
http://www.mydomain.com/my info.html
