Looking at the tests, that seems to be desired behavior.<br>
</div><div><br></div><div>Looking at RFC 2049 I think the correct response is "206 partial". From <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html</a> :</div>

The request MUST have included a Range header field (section 14.35) indicating the desired range, and MAY have included an If-Range header field (section <a rel="xref" href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.27">14.27</a>) to make the request conditional.</p>
<p style="color:rgb(0,0,0);font-family:Times;font-size:medium">The response MUST include the following header fields:</p><pre style="color:rgb(0,0,0)"> - Either a Content-Range header field (section 14.16) indicating
the range included with this response, or a multipart/byteranges
Content-Type including Content-Range fields for each part. If a
Content-Length header field is present in the response, its
value MUST match the actual number of OCTETs transmitted in the
message-body.
</pre><pre style="color:rgb(0,0,0)"> - Date
</pre><pre style="color:rgb(0,0,0)"> - ETag and/or Content-Location, if the header would have been sent
in a 200 response to the same request
</pre><pre style="color:rgb(0,0,0)"> - Expires, Cache-Control, and/or Vary, if the field-value might
differ from that sent in any previous response for the same
variant
</pre><p style="color:rgb(0,0,0);font-family:Times;font-size:medium">If the 206 response is the result of an If-Range request that used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. If the response is the result of an If-Range request that used a weak validator, the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers. Otherwise, the response MUST include all of the entity-headers that would have been returned with a 200 (OK) response to the same request.</p>
<p style="color:rgb(0,0,0);font-family:Times;font-size:medium">A cache MUST NOT combine a 206 response with other previously cached content if the ETag or Last-Modified headers do not match exactly, see <a rel="xref" href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13.5.4">13.5.4</a>.</p>
<p style="color:rgb(0,0,0);font-family:Times;font-size:medium">A cache that does not support the Range and Content-Range headers MUST NOT cache 206 (Partial) responses.</p></div><div><br></div><div><br></div><div>-- <br>
