What about your actualy ProxyPass directives and other associated options? Ans: Just regular configurations... all of them like this: ProxyPass /path https://server.internal.net/path Do only certain browsers trigger the problem (trying to figure out why you shared the above)? Ans: No, all of them do. Are you running mod_security or some other Layer 7 security tool? Ans: No Is the issue reproducible enough that you'd be able to capture a pcap dump of a "broken" request? Ans: Yes, we got a pcap but it's SSL on both directions (from Internet to proxy and from proxy to internal server.) Has the problem always existed? If not, when did it start? Ans: This is the first time we are trying it in our test environment. Thanks again for your help.
