<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I guess the parser just lowercases the key ("keep-alive"), not the values. Lowercasing the keys is okay because per the spec they are case-insensitive, and it has the advantage that you can look up keys in more or less constant time when using a hashtable.
In many cases the values are case sensitive (usernames, something Base64-encoded for example), so the parser better leaves them alone. So you need to normalize the case yourself.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Small addition: The values are key-value pairs again here, but that isn't universally so in HTTP headers. The header parser simply doesn't know about such details.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Keep-alive header can specify multiple, comma-separated, value pairs.
For example what apache web server normally sends is something like that:
"Keep-Alive: timeout=5, max=99"
Actually kio_http fails to extract timeout value because it assumes
keep-alive header can contain only a single value pair.
In the case of example above what it end up to do is
m_request.keepAliveTimeout = QString("5, max=99").toInt(), that returns 0 (wrong!).

-Hacked a web server and made tests against following keep-alive header variants:
"Keep-Alive: timeout=5, max=99"
"Keep-Alive: Timeout=5, max=99" (uppercase 'T')
"Keep-Alive: Timeout=5 , max=99" (extra space before comma)
