I am currently working on tomcat4.1.
And it looks like that there is no difference in Absolute and relative path.
It does not matter whether I am using href="myPage01.html" or href="/myPage01.html".
Both points to "myContext/myPage01.html".
Though the calling/source page[where this link is available] is in myContext/dir01/dir02/callingPage.html.
