I did some more experimenting with which URLs retrieve ok and which ones don't
and have a new test program. With this test program url2,4,5,8 have errors. the
other
urls retrieve ok. So, I tried to identify what is unique about the urls that
fail. All of these
are a list of up to 25 items per page. The pages that have a full 25 items all
seem
to work ok. Some, but not all of the partial pages fail.
from firefox page info:
url2 length 5,235
url4 length 7,101
url5 length 5,249
url8 length 4,952
url7 length 2,675 (this is a partial page that retrieves ok)
My theory is there is a problem with page lengths in the 4K-8K range.
Also seems to be unique to this site as I've been unable to reproduce on other
sites.
I am also wondering if the partial pages have some unusual data in them (such as
a strange hexadecimal character) but I haven't identified anything like that.
