URL encoding for links w/ PL/SQL

[Quoted] How do I format a string variable to be used as an URL?

I have some string values containing spaces and ampersands, and they don't create the proper links. ie: the following produces a result that does not work.
value = "Big & Burly"
htp.prn("/my_page?in_value='||value);
[Quoted] [Quoted] creates link "/my_page?in_value=Big & Burly", which passes an incoming parameter of "Big " as the & character seperates values in an URL.

I know ASP uses a URLEncode function. What is the equivalent in PL/SQL?
