HTTP/1.1 200 OK
Server: Oracle-Application-Server-11g
Transfer-Encoding: chunked
Via: 1.1 www.ilo.org
Transfer-Encoding: chunked


The above (abridged) response is malformed because it has two 
Transfer-Encoding headers signalling "chunked, chunked" transfer 
encoding. The proxy and/or the origin server your Squid is talking to is 
broken.


Modern Squids reject such messages because they are known to be used for 
cache poisoning and other security breaches. There is no official 
workaround (yet).



HTH,

Alex.

Thank you for your reply!
I've increased the debuglevel, but can't find any reason, why squid
reponds with ERR_INVALID_RESP.

Maybe someone with more knowledge can find the reason in the cache.log.
It can be found here: https://bloms.de/download/cache.log.gz

TLS is complicated. SSL-Bump even more so. It is unlikely everyone else 
has exactly the same things occuring, even if they have the same 
squid.conf settings.


You need to look at what the ERR_INVALID_RESP actually says in wrong 
with the server response.
The check Squid cache.log. You may need to set "debug_options 11,2" to 
get a trace of the HTTP messages and see what is going on.

[squid-users] squid 5.7: can't access https://www.ilo.org/global/lang--en/index.htm with enabled sslbump, without sslbump it works

Hello,

I'm using squid 5.7 with enabled sslbump and can't reach the website 
https://www.ilo.org/global/lang--en/index.htm
I get an error of type ERR_INVALID_RESP, but when I disable sslbump the
webcontent is shown in the browser.

Can anybody confirm this and can tell me what causes this problem ?
