Hi,


I want to get part of the data according to as I submit the input from other web sites . I am using a Tomacat server .

My actual requirement is that i have to get all metabolic path ways from the url

eg. http://www.systems-biology.org/001/kegg/aae.html

KEGG link

Any one suggest a solution?

Requesting partial content can be done using the HTTP header Range:, but I can't understand that how is it related to fetching some specific links from a page. I guess You need to parse the links in the page to do so.
