Hello,
I'm having issues copying a recipe to the cloud folder with the following error (see below) running on BeerSmith 2.1.02. I am running Squid as the proxy on my firewall, and the error from Squid is:
HTTP/1.0 417 Expectation failed
Server: squid/2.7.STABLE9
Date: Fri, 19 Oct 2012 18:46:44 GMT
Content-Type: text/html
Content-Length: 1372
X-Squid-Error: ERR_INVALID_REQ 0
X-Cache: MISS from localhost
X-Cache-Lookup: NONE from localhost:80
Via: 1.0 localhost:80 (squid/2.7.STABLE9)
Connection: close
It is my understanding that Squid's internal engine only proxies HTTP 1.0 requests, and the Expect: 100-Continue is HTTP 1.1. According the the RFCs a client is supposed to receive the 417 error message and retry with 1.0. Please see:
