> Project: Wink
> Issue Type: Bug
> Components: Server
> Affects Versions: 0.2
> Environment: IBM Lotus Expeditor's Web Container - LWI 7.1.1.
> Reporter: Kaloyan Kolev
> Assignee: Bryant Luk
> Fix For: 0.2
>
>
> The
> org.apache.wink.server.internal.contexts.HttpHeadersImpl#getRequestHeaderInternal(String)
> gets the values of the Accept header from an instance of the
> javax.servlet.http.HttpServletRequest which in our case is of type
> com.ibm.ws.webcontainer.srt.SRTServletRequest. The returned enumeration of
> header values contains the following elements:
> [text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8, null, null,
> null, null, null, null, null, null, null]
> The HTTP Request headers looks like this:
> Host: localhost:13100
> User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.1.3)
> Gecko/20090824 Firefox/3.5.3

> Accept-Encoding: gzip,deflate
> Accept-Charset: windows-1251,utf-8;q=0.7,*;q=0.7
> Keep-Alive: 300
> Connection: keep-alive
