Subject: Campus Proxy Servers
A request for help from anyone who subscribes to Historical
Abstracts via the WWW (or uses any other Web services that use an
incoming port other than port 80), please. (Apologies to anyone
who's already received this message.)
We at the University of Sussex Library have decided to take out a
subscription (we have agreed this with ABC-Clio, the producers, but
money has not yet changed hands). The pre-Christmas trial we had
worked perfectly, but now it is impossible for us to connect.
After a lot of investigation, the reason turns out to be that
ABC-Clio have just started using port 81 rather than the standard
for Web servers, port 80. (To put it more technically: calls to
Historical Abstracts at ABC-Clio's site are intercepted by a load
balancer on the default port of 80 and redirected to one of two
separate servers that use port 81.)
Our Computing Service requires calls from most machines on campus to
go via a proxy server. One consequence is that access to http
servers which do not use port 80 for incoming calls is blocked.
Obviously, we're trying various approaches to solve this problem,
but could I ask whether anyone else subscribing to Historical
Abstracts (or any other product using a non-standard incoming port)
from a campus operating a proxy server/firewall system is
experiencing any similar problem, please? If so, did you find a way
round it?
Thanks in advance.
