[squid-users] TCP_MISS/000 0 POST

I have a TCP_MISS 000 error being reported for users in the subnet attempting to upload files to a particular internet site. I understand that 000 indicates that the request has been aborted before it could complete? The exact error is:

TCP_MISS/000 0 POST http://[domain removed ]/fileuploads? - DIRECT/domain removed

I have also tried sending direct via the Squid to no avail - if I bypass the Squid entirely it works ok.

Any help gratefully received!
