Aggregate to the supplied chain, HTML to manifest a button. The button can be a link (GET request) OR a form action (POST request). In the link case, button member m_Linkto will give the location. In the form action case, there will need to be submission URL which is obtained from the form reference (given in HTTP event variable m_pContextForm). Returns: None

Function body:
