[Caml-list] escape characters in a cgi parameter

[Caml-list] escape characters in a cgi parameter

[amata]

  Hi list.

  I´m using the CGI library in order to receive arguments in a CGI 
application. I use the function "parse_arguments" for parse the CGI 
arguments. 

  My problem is; when I receive the cgi parameters, if one of the 
parameters include one of this characters: = or & the function 
parse_arguments returns one exception. I must escape the characters = 
and &, but how can I do that? Anybody knows how to escape characters 
in a cgi parameter? 

   Thank you very much.

Yes, you should certainly escape these characters, and more. Look on
Google for information about "percent escaping" and "url escaping".

BTW have you tried using mod_caml for your scripts?

  Thanks Richard!!

  You was right. Escape characters is very easy. You must put the 
character % and then the ASCII number in hexadecimal. 

  For example, if you want to escape the character =, you must write 
 %3D (3D is the ASCII number of the character = in hexadecimal)
