<p class="MsoNormal">Hi, I am using Varnish in front of the Caringo CAStor storage system.<o:p></o:p></p>
<p class="MsoNormal">CAStor requires Varnish to perform the actions described below, is this possible? (basically I would need some kind of ‘God mode’ for the backends, or I need to bypass the director – or make my own director)<o:p></o:p></p>
<div style="mso-element:para-border-div;border:none;border-bottom:solid windowtext 1.0pt;padding:0cm 0cm 1.0pt 0cm">
<p class="MsoNormal" style="border:none;padding:0cm"><o:p> </o:p></p>
<p class="MsoNormal" style="border:none;padding:0cm">( the redirects occur on PUT-POST-GET-HEAD)<o:p></o:p></p>
<p class="MsoNormal" style="border:none;padding:0cm"><o:p> </o:p></p>
<p class="MsoNormal" style="border:none;padding:0cm">Thanks in advance.<o:p></o:p></p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p>Client applications must be able to accept and properly interpret two different<br>
kinds of redirect responses. If CAStor returns a <span class="italic">301 Moved Permanently</span> response, this means the Primary Access Note<br>
(PAN) is asking the client to resend the current request to the <span class="italic">
location</span> supplied in the response headers (see <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.2" target="_top">
Section 10.3.2</a> of the HTTP/1.1 spec) <span class="italic">and</span> to direct all future requests to that new node until further<br>
notice.<o:p></o:p></p>
<p>An authorization parameter will be supplied in the location header. This<br>
parameter should be included in the request to the new PAN. It is possible that a<br>
future <span class="italic">Moved Permanently</span> will be received<br>
redirecting to yet another PAN (in that respect, the response is slightly<br>
misnamed).<o:p></o:p></p>
<p>The second type of redirect response CAStor might send is the <span class="italic">
307 Temporary Redirect</span>. This response asks the client<br>
to resend the current request to the <span class="italic">location</span><br>
supplied in the response headers, but to continue using the original PAN for the<br>
next request until further notice.<o:p></o:p></p>
