commons-httpclient-3.1 not parsing the multi-line response headers correctly
----------------------------------------------------------------------------
Key: HTTPCLIENT-845
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-845
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient
Affects Versions: 3.1 Final
Environment: Win 2003
Reporter: Robin Gandhi
Priority: Blocker
The parseHeaders() methods inside the HttpParser
class(org.apache.commons.httpclient.HttpParser) is not parsing the Multi-line
response heders correctly.
For example if it recieves the below response:
HTTP/1.1 200 OK\r\n
Connection: line-1\r\n
X-Multiline: line-0\r\n
\t line-1: value\r\n
\t line-2: value\r\n
\t line-3: value\r\n
\t line-4: value\r\n
\t\r\n
\t line-6: value\r\n
\t line-7: value\r\n
\t line-8: value\r\n
\t line-9: value\r\n
\t\r\n
\t line-11: value\r\n
\t line-12: value\r\n
\t line-13: value\r\n
\t line-14: value\r\n
\t\r\n
\t line-16: value\r\n
Date: Wed, 10 Dec 2008 08:03:34 GMT\r\n
Content-Length: 15\r\n
Connection: close\r\n
\r\n

It will consider the first few lines(as shown blow) as response headers but
whaever is there after "\t\r\n" it considers it as response data due to the
presence of blank line
HTTP/1.1 200 OK\r\n
Connection: line-1\r\n
X-Multiline: line-0\r\n
\t line-1: value\r\n
\t line-2: value\r\n
\t line-3: value\r\n
\t line-4: value\r\n
Http Specs say that "HTTP/1.1 header field values can be folded onto multiple
lines if the Continuation line begins with a space or horizontal tab".
In the above case even though the line is starting with tab("\t\r\n")
HttpParser class is not considering it as part of Multi line response header.
