URL Encoding
The syntax of URLs is formally defined in RFC 1738.Not all ASCII characters are permitted in URLs.
Non-permissible characters, such as `<' and `>', and characters that have a special meaning, such as `/' and `:', must be encoded by a percent sign (`%') followed by two hexadecimal digits (0--9, A--F) giving the ordinal value for that character in the ISO 8859 character set.
The table shows a number of common encodings.
Note that encoding and decoding is quite straightforward.
+ %2B
& %26
= %3D
/ %2F
~ %7E
% %25
space %20
Sample Code for encoding data part of URL's
;Encoding sample code
Line=AskLine("Enter your line","Right here","A Sample Line")
line=strreplace(line,"%","%25") ;MUST DO %'s first !!!
line=strreplace(line," ","%20")
line=strreplace(line,"~","%7E")
line=strreplace(line,"/","%2F")
line=strreplace(line,"=","%3D")
line=strreplace(line,"&","%26")
line=strreplace(line,"+","%2B")
