URL-Encoding

The request and response are URL-encoded. URL-encoding ensures that you can transmit

special characters, characters that are not allowed in a URL, and characters that have special

meaning in a URL, such as the equal sign and ampersand. For example, the following NVP

string:

NAME=Robert Moore&COMPANY=R. H. Moore & Associates

is URL-coded as follows:

NAME=Robert+Moore&COMPANY=R%2E+H%2E+Moore+%26+Associates

Use the following methods to URL-encode or URL-decode your NVP strings:
