Hi,
Today I have put further load on ATS on the fly (redirected port 80=20
towards ATS box). The site running nginx caused the 502 error (in the=20
squid logs) I tried the workaround of disabling keep_alive for sometime=20
and restarting services which resolved the issue but now im seeing the=20
following in the error.logs:


Error Log Output:
20160317.23h36m39s RESPONSE: sent CLIENT-IP status 502 (Connect Error=20
<Connection refused/111>) for 'http://download.foobar.com/1GB.zip'
20160317.23h36m40s RESPONSE: sent CLIENT-IP status 502 (Connect Error=20
<Connection refused/111>) for 'http://download.foobar.com/1GB.zip'

20160317.23h36m40s RESPONSE: sent CLIENT-IP status 502 (Connect Error=20

But I also see the following in Squid.blog: What does it mean?
