I have some squid's running on rocky linux 8 with verion 4.15, recently
been testing squid version 5.2(stable version that comes with Rocky 9)to
upgrade the current ones and most of the configs/acls seem to work fine.
Unfortualy theres an application that we use that everytime it tries to
upload files it fails on squid 5.2, on 4.15 is works completly fine, so
far ive test on squid 5.2 and 5.5 and it's the same behavior, im testing
this with default configurations and it always works on 4.15, access log
only shows this:
Squid 4.15:
26/Aug/2022:15:36:08 +0100 273 172.19.222.132TCP_MISS/200 745 POST http://websiteurl/index.php - HIER_DIRECT/websitedomain text/xml
Squid 5.2:
25/Aug/2022:15:10:00 +0100 139 172.19.222.132 TCP_MISS_ABORTED/100 0 POST http://websiteurl HIER_DIRECT/websitedomain -
anyone has an ideia of what may be happening here?, been searching about
http errors 100 and so far i did not find anything that points me to the
problem.
On the application side the error it shows when it tries to upload is:
"
Error storing the document on the server
Detail HTTP error 100
Send failure: Connection was aborted (55)
"
Squid v5.2 has many serious bugs. I would not use it in production.
Build the latest Squid v5 from sources if you have to.
If the latest Squid v5 shows the same problem then this is probably a
client application or Squid bug/misconfiguration. There were quite a few
changes in HTTP 1xx control message handling since Squid v4, and one of
those changes is probably affecting your client. For example, either
Squid v4 does not deliver that 100 control message to the client at all
or it is delivering a slightly different 100 control message that your
client is happy with.
If you share what HTTP messages are exchanged between client and Squid
and between Squid and the origin server, in both successful and failing
use cases, we may be able to tell you more. I would use tcpdump,
wireshark, or a similar tool to collect HTTP traffic since these are
non-TLS transactions.
