Invalid Header
--------------
Key: HTTPCORE-274

Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 4.2-alpha1
Environment: windows7, ie9, chrome13, jdk7
Reporter: yangqing
Priority: Minor
When I tried to get a page using HttpClient, I got the exception below, the url
is "http://ss.97down.info/mimi/file.php/L87S8KD.html";.
Caused by: org.apache.http.ProtocolException: Invalid header: <meta
http-equiv="Content-Type" content="text/html; charset=utf-8" />

The page can be displayed normally in IE and Chrome. I traced the source code
of HttpCore, and find this line in BufferedHeader.java,
int colon = buffer.indexOf(':');
I found that except other normal headers, there was really an odd header, the
value is :
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
The format is ugly, there is no colon in it, and caused an exception.
The orginal header the Chrome gets is like:
HTTP/1.1 200 OK
Connection: close
Date: Sat, 04 Sep 2010 08:46:38 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-Powered-By: PHP/5.2.8
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
Content-type: text/html
Yes, it's malformated, but Chrome parsed it as:
Connection:close
Content-type:text/html
Date:Sat, 04 Sep 2010 08:46:38 GMT
Server:Microsoft-IIS/6.0
X-Powered-By:ASP.NET
PHP/5.2.8
I then and a snippet in the for loop of the parseHeaders method of the class
AbstractMessageParser.java to ignore this type of error.
if(current.indexOf(':')<=0){
continue;
}
It works for me, I hope someone can fix this problem.
Thanks!
