[jira] Created: (HTTPCORE-202) Expect header value sent as
"100-Continue" and not "100-continue"
Expect header value sent as "100-Continue" and not "100-continue"
-----------------------------------------------------------------
Key: HTTPCORE-202
URL: https://issues.apache.org/jira/browse/HTTPCORE-202
Project: HttpComponents HttpCore
Issue Type: Bug
Reporter: Robert Newson
According to http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html, the Expect header should use "100-continue". HttpClient sends "100-Continue" instead which is not recognized by some clients (mochiweb, for example) which is expecting the canonical form. While clients should be tolerant, HttpClient should be strict in what it sends.
This causes HttpClient to block for two seconds waiting for the "HTTP 1.1 100 continue" response before it times out and posts the request body, a significant penalty.
The code in question is here;
./httpcore/src/main/java/org/apache/http/protocol/HTTP.java: public static final String EXPECT_CONTINUE = "100-Continue";
A reciprocal bug is reported against mochiweb to be more tolerant at http://code.google.com/p/mochiweb/issues/detail?id=42

[jira] Commented: (HTTPCORE-202) Expect header value sent as
"100-Continue" and not "100-continue"
Posted by "Robert Newson (JIRA)" <ji...@apache.org>.

Robert Newson commented on HTTPCORE-202:
----------------------------------------
To clarify, I understand that the spec is clear that "100-continue" must be treated case-insensitively. The real bug is in mochiweb which only matches "100-continue". Sending "100-continue" is still preferred for clients with similar bugs.
