Issue with collapsed forwarding plugin, one CONN_FAIL
Ive been testing the collapsed forwarding plugin here by sending it random traffic, one request with 10 duplicates of the same request. One thing Im seeing is that a lot of the time one of the requests out of those 10 will come back as an ERR_CONN_FAIL, but the pssc will be the 303 redirect.
I was just wondering if this was expected? Is it an issue or has anyone seen this?
Here is my output logging showing one of these instances:

RE: Issue with collapsed forwarding plugin, one CONN_FAIL
Posted by "Chou, Peter" <pb...@labs.att.com>.
Evan,
I saw something similar with 304 instead of 303 when I tried something similar earlier. You can check my e-mail in the mailing list archive -- it was sent on 6-23-2017.
BTW, the issues I described were reproducible on my dev machine using curl and bash/perl to generate the requests. When we moved to our test environment with production level machines and using Spirent to generate traffic they were not reproducible. Perhaps some kind of timing issue in a low performance environment (the test machine and network were virtualized)?
Thanks,
Peter
