Check that you do have the comma in Plone's caching control panel. I can imagine it being an easy typo to make.<div><br></div><div>There are many unique variations of Accept-Language headers, so be careful. I've used this before in vcl_recv to normalise the incoming request:</div>
<div><br></div><div><div> # We only care about the language in the I18N_LANGUAGE cookie</div><div> if (req.http.Cookie ~ "(^|.*; )I18N_LANGUAGE=") {</div><div> set req.http.Accept-Language = regsub(req.http.Cookie, "(^|.*; )I18N_LANGUAGE=([^;]*)(; .*|$)", "\2");</div>
<div> # XXX need to work out the proper way to match " here, e.g. "en"</div><div> set req.http.Accept-Language = regsub(req.http.Accept-Language, "^.(.*).$", "\1");</div><div> } else {</div>
<div> set req.http.Accept-Language = "en";</div><div> }</div></div><div><br></div><div>Laurence</div><div><br><div class="gmail_quote">On 1 July 2010 22:04, Ken Brownfield <span dir="ltr"><<a href="mailto:kb%2Bvarnish@slide.com">kb+varnish@slide.com</a>></span> wrote:<br>
