What HTTP client are you using (Pecl_Http, fopen, or Curl)? In my case fopen is used by kronolith. Is this changeable?

Great. So even though we are not sending any actual expectations, Squid is telling us that it can't meet the expectation. Wonderful.

I discovered a problem as I wanted to add an external calendar from a server which is behind a Squid Proxy: Horde sends an empty Expect-Header and Squid rejects this with an 417 Error. As I removed the Expect-Header in /usr/share/php/Horde/Core/Factory/HttpClient.php it worked, but I don't know if the header is required somewhere else.
