%23 in querystring

[Jeremy]

I'm trying to understand the following part of a QueryString value: What
does the %23 mean? I presume that the 'efefef' is a color (RGB) value. What
about the '&'. I thought the ampersand (&) signaled another variable in
the querystring - but apparently not in this case?

BG=%23efefef&

Here's the entire querystring:
<form name="Form1" method="post"
action="Select_Destination.aspx?PG=ID3&amp;BG=%23e fefef&amp;template=templat
e4.htm" id="Form1">

Thanks

Jeremy,

The query string you are looking at has been urlencoded so that characters
that would normally make the url error out may be passed in the query
string. For example: %23 is the url encoding for a "#" symbol.

Here is a list of common urlencodings:

We do url encoding and decoding because in the RFC 1738
specification of URL (which defines the standards of url),
it limits URL to contain only 0-9 a-z, A-Z and $-_.+!*'(), characters.

So we needed a way to pass those characters which are not
supported by url specification.. so we have a way to pass the chars
in encoded format (%23) in url and convert it back to its orignal
form on server side (#)

In addition, you can use HttpUtility.UrlDecode() to convert the special
characters back to their original.
