According to Jason Hunter's book some browsers send the 'If-modified-Since'
header to make use of the Conditional GET support (that is the content body
will be sent to the client only if it
is modified). However i checked up all the request headers sent by IE5.0 and
Netscape 4.7 as well as Opera but none of these browsers sent the header
'If-Modified-Since'.
Can you tell me why? and secondly does this mean that the getLastModified()
of the HttpServlet will be of no use for such cases?
Any help will be appreciated
thanks,
Nitin
