Hi KrishnanIyer,
You can try using
int web_convert_param( const char *ParamName, [char *SourceString] char *SourceEncoding, char *TargetEncoding, LAST );
You can choose from HTML, URL and Plain source and target encodings.
For additional details and examples please check LoadRunner Function reference.
You have converted C_ssotoken1 to URL encoding. Please check in what format the server expect the request form the client and decided if "CONVERT=HTML_TO_URL" is needed.
Kind regards,
Vesela
