----------------------------------------
for example, with the site:
http://www.noormags.com/view/fa/default
when fetch the first page, and dump from segment, see that there is a problem with fetch,
when i replace
byte[] content = DeflateUtils.inflateBestEffort(compressed, getMaxContent());
with
byte[] content = DeflateUtils.inflateBestEffort(compressed, 99999999999);
it's work
