[squid-users] Squid 5.2 TCP_MISS_ABORTED/100 erros when uploading

[David Ferreira]

hi,

First time using mailing lists, sorry about anything.

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    273 172.19.222.132 TCP_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/index.php - 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)
"

Thanks in advance,

David
