Just encode the urls twice.

In php, it would be:

$link = 'foo.cgi?uri='.urlencode($uri).'&foo='.urlencode($foo);

print '<a href="';
print htmlspecialchars($link);
print '">Clicketi click</a>';

Got it? Urlencode the parameters, and
htmlencode the anchor href-parameter,

urlencode() encodes any & to %26, and
htmlspecialchars() encodes any & to &amp; .
