Hi,
Many appologies if this is not the correct place to ask about
svn's dav support, if so please rediect me.
AS per the subject, SVN's WebDAV server does not seem to
be honouring partial HTTP GETs even though it appears to
offer the facility with
Accept-Range: bytes
To demonstrate use wget (on windows or Linux), using the command line
interrupt the processing once the transfer has begun.
wget -d -c
http://svn.apache.org/repos/asf/db/ddlutils/trunk/lib/build-only/ant-1.6.5.jar
now re-run the command and you will notice the Range: request and the
Accept-Range: reply but no Content-Range: and the whole file is downloaded
again (see below)
Googleing I found references to partial PUTs being supported (A grey area in
the spec I beleive) but nothing about partial GETs being supported or not.
I looked at the svn issue tracker and could find no mention of this there
either.
Would you expect svn to support partial gets? Is SVN likely to support
partial GETs in the future?
Am I asking in the wrong place?
FWIW I am writing a WebDAV client to access SVN repositories for
plan9.
Thanks for any/all help.
-Steve
