Hello all,<br>
<br>
The code for the proposed conditional backend request feature (usually<br>
If-Modified-Since requests to backends) is now up to date with the<br>
current trunk and available on an experimental branch of the source<br>
repository called experimental-ims.<br>
<br>
On an updated git working tree you can say:<br>
<br>
$ git branch -a<br>
<br>
... and you should see something like 'remotes/origin/experimental-ims'<br>
in the list. Then to work with the branch:<br>
<br>
$ git checkout -b experimental-ims remotes/origin/experimental-ims<br>
<br>
To switch back to the master branch:<br>
<br>
$ git checkout master<br>
<br>
The feature is documented here:<br>
<br>
<a href="http://www.varnish-cache.org/trac/wiki/BackendConditionalRequests" target="_blank">http://www.varnish-cache.org/trac/wiki/BackendConditionalRequests</a><br>
<br>
Please note that this code is experimental, and will not be included in<br>
the upcoming 3.0.0 release. The way that this works has not been changed<br>
from the previous versions distributed as patches, but will likely be<br>
changed in future versions.<br>
<br>
Testing the mainline 3.0 version is the highest priority for the Varnish<br>
team right now, so feedback on that is most important. If you also get a<br>
chance to test the IMS feature, it will be a great help toward getting<br>
an "official" version settled, so let us know how it goes.<br>
<br>
<br>
Best,<br>
Geoff<br>
