Subject [jira] Created: (GERONIMO-3857) response header parsing is done incorrectly
Date Fri, 15 Feb 2008 07:29:07 GMT
response header parsing is done incorrectly
-------------------------------------------

                 Key: GERONIMO-3857
                 URL: https://issues.apache.org/jira/browse/GERONIMO-3857
             Project: Geronimo
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: AsyncHttpClient
    Affects Versions: 1.x
            Reporter: Sangjin Lee
            Assignee: Rick McGuire


When we decode response headers, HttpDecoder separates name from value using ": " (note the
*single*space after the colon).  This is incorrect.  The HTTP spec says

- The field value MAY be preceded by any amount of LWS, though a single SP is preferred.

The separator pattern should be simply ":".  Then any preceding or trailing LWSP characters
(SP or HT) should be removed from the value.  This is a rather critical issue.  I had headers
like 

Server: Foo
Content-Length:62
Connection: close

(notice lack of space after "Content-Length:")

HttpResponseDecoder cannot properly parse the above headers, and throws a StringIndexOutOfBoundsException.
