    "RB='",
    "Ord=1",
    "RelFrameId=1",
    "Search=Body",
    "IgnoreRedirections=Yes",
    LAST);

The original value of sessionId will be replaced with {WCSParam_Text1}

web_submit_data("login.action",
    "Action=https://.../login.action",
    "Method=POST",
    "RecContentType=text/html",
    "Referer=https://...",
    "Snapshot=t50.inf",

    ITEMDATA,
    "Name=Lang", "Value=en", ENDITEM,
    "Name=sessionId", "Value={WCSParam_Text1}", ENDITEM,
