URL Encoding

According to HTTP specifications, unsafe characters included in transmitted data with the MIME type application/x-www-form-urlencoded must be encoded (escaped). This is achieved by replacing unsafe characters with hexadecimal equivalents and preceding them with percent (%) symbols.

Silk Performer provides four standard encoding types: ENCODE_FORM, ENCODE_ESCAPE, ENCODE_BLANKS and ENCODE_NONE. These encoding types differ in terms of the characters they escape.

Siebel Web client Java applets apply a unique encoding type that differs from the standard Silk Performer encoding types. For this reason, Silk Performer provides a new encoding type, ENCODE_CUSTOM, which can be configured using the function WebFormDefineEncodeCustom.

Siebel uses an encoding type that differs from the standard encoding type ENCODE_FORM in the following respects:

The Silk Performer Web Recorder detects when an HTTP request applies this special encoding type, and then generates a script using the following techniques:

This example shows fragments of a recorded script that utilizes these techniques.
