道
道可道﹐非常道。
名可名﹐非常名。
無名天地之始﹔有名萬物之母。
故常無，欲以觀其妙﹔常有，欲以觀其徼。
此兩者﹐同出而異名﹐同謂之玄。玄之又玄﹐眾妙之門。
============================================
道 並非是單純的
是以相反的概念 所相互伴隨著的
如果要真的要了解"道"
就要由相反的概念去尋找
相反的概念其實是相同的根源
但卻是了解真理奇妙之處的入門法則

So here question is arises what is multipart boundary and why use it? The Content-Type field for multipart entities requires one parameter, "boundary", which is used to specify the encapsulation boundary. The encapsulation boundary is defined as a line consisting entirely of two hyphen characters ("-", decimal code 45) followed by the boundary parameter value from the Content-Type header field.

Things to Note...
