Yes, the patch did not make it to 2.4.39 which was mainly a security release, and this change is not really trivial.. Hopefully 2.4.40 is coming soon.

This causes a client to think it should write a request body, while the backend may still respond with a 400 and not read the request body. mod_proxy_http then responds with 502 as a result of AH01097: pass request body failed The backend is doing the right thing: it did not send a 100 continue so it should not be required to read a request body, regardless of transfer encoding or content-length. Expected: mod_proxy_http reverse proxy should not send 100-continue to a client unless the backend does.

[Bug 1641238] Re: as a reverse proxy, a 100 continue response is sent prematurely when a request contains expects: 100-continue
Hi Robie, The specific need is that www.jujucharms.com uses apache2 as a reverse proxy to charmstore. The upload of resources and charms is suboptimal without 100-continue support. While investigating adding 100-continue support, we ran into this bug. As for a general need for this to be fixed in Ubuntu, I know of none, other than correctly supporting 100-continue in http reverse proxies. Only Ubuntu users using mod_proxy_http to reverse proxy a service which implements 100-continue are impacted by this problem. There must not be any. I'm honestly surprised that this bug has existed for so long. I am working with upstream to get this or a similar patch applied. I'll continue doing so.

Thank you for taking the time to report this bug and helping to make Ubuntu better. I think we should wait until upstream commits a fix for this before we do anything in Ubuntu. Or is there a specific need that requires this to fixed sooner in Ubuntu? Under what circumstances are Ubuntu users impacted by this problem? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641238 Title: as a reverse proxy, a 100 continue response is sent prematurely when a request contains expects: 100-continue To manage notifications about this bug go to: https://bugs.launchpad.net/apache2/+bug/1641238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1641238] [NEW] as a reverse proxy, a 100 continue response is sent prematurely when a request contains expects: 100-continue
Public bug reported: This effects trusty, xenial and current httpd trunk. https://bz.apache.org/bugzilla/show_bug.cgi?id=60330 As a reverse proxy, a 100 continue response is sent prematurely when a request contains expects: 100-continue. This causes the requesting client to send a body. The apache httpd proxy will then read the body and attempt to send it to the backend, but the backend already sent an error and should be allowed to NOT read the remaining request body, which never should have existed. When the backend does not read the request body mod_proxy_pass errors and returns a 500 error to the client. The client never receives the correct error message. ** Affects: apache2 Importance: Unknown Status: Unknown ** Affects: apache2 (Ubuntu) Importance: Undecided Status: New ** Bug watch added: bz.apache.org/bugzilla/ #60330 https://bz.apache.org/bugzilla/show_bug.cgi?id=60330 ** Also affects: apache2 via https://bz.apache.org/bugzilla/show_bug.cgi?id=60330 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641238 Title: as a reverse proxy, a 100 continue response is sent prematurely when a request contains expects: 100-continue To manage notifications about this bug go to: https://bugs.launchpad.net/apache2/+bug/1641238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
