Re: Gale database 400 errors

It's more of an EZproxy problem, not specifically a certain browser or
database provider.

When a provider's site want to set one or more cookies and you're accessing
through the proxy, the proxy makes one cookie to hold all the required
data. Go to a different provider, and now that cookie also contains the new
provider's data. Eventually, if you visit enough different sites, the
cookie EZproxy is using will grow larger than the max allowed size, so new
data cannot be added to that cookie. For many providers, you'll then see
weird server errors, because they expect to be able to write and read to
their cookies, but on your browser, it's just that now-oversized cookie
that can't accept any more data. So clearing your cookies resets it back to
zero, ready to start accepting new data again.

Users who only use a few databases will never see this error. Librarians
who use many databases will see this problem more frequently. Option
DomainCookieOnly can help with certain providers but will definitely break
others.
