[Gnu-arch-users] tla seeing stale .listing files through caching web proxy

[Richard Curnow]

I'm accessing a remote http: repository through a caching web proxy.  (I
can't connect directly since this is at work.)  If I run 'tla revisions'
on this repository, I get an out-of-date listing with the latest
revisions missing.  However, I can access the same .listing file through
Mozilla or wget and receive back an up-to-date copy.

Here's an excerpt from the tla strace:

3320  write(7, "GET

3320  select(8, [7], NULL, NULL, {120, 0}) = 1 (in [7], left {120, 0})

and from the wget strace:

19619 write(4, "GET

Both clients seem to be getting cache hits from the proxy, but tla is
being given an out of date file.  I can't find anything I can change in
tla to fix this (e.g. HTTP/1.1 v 1.0 looks like an obvious candidate to
try changing, but AFAICS there's no way to adjust this from the command
line) - or is the problem with the web proxy?
