You mean a hyperlink? Hyperlinks are URL - they must be URL encoded.
Characters like '&' separate query string parameters in HTTP GET requests,
so if you have an ampersand ('&') that is not a delimiter in a query string then
the URL must URL-encode it as "%26".

So if you had a URL in the request like,

http://www.example.com/merger.aspx?acquirer=SBC&acquiree=AT&T

Then the '?' separates the endpoint on the web server,
"http://www.example.com/merger.aspx," from the query string which
contains two parameters, each separated by '&',

Name = acquirer Value = SBC
Name = acquiree Value = AT&T

Notice that when performing the URL decoding step, the '&' character
that is part of the parameter value gets converted back from "%26" to
'&'. 0x26 hex, by the way, is that character code of '&'.

Javascript includes an encode( ) function for performing these URL
encoding duties.
