Sebb commented on HTTPCORE-274:
-------------------------------
That is an invalid header.
The server is misbehaving; it should never send such a header, so HC is correct
in reporting it.
It might however be worth enhancing HC to optionally log the error rather than
throw an Exception; that would allow clients to ignore the error.
> Invalid Header
> --------------
>
> Key: HTTPCORE-274
> URL: https://issues.apache.org/jira/browse/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!
