Subject: Add Content-Length header to thumb.php redirects
X-Git-Tag: 1.31.0-rc.0~10594^2
X-Git-Url: http://git.cyclocoop.org/%22%2C%20generer_url_ecrire%28?a=commitdiff_plain;h=304e95a3337b9e961feab77fe36ace9e0cd57401;p=lhc%2Fweb%2Fwiklou.git

Add Content-Length header to thumb.php redirects

Without the Content-Length header, the response is sent with
Transfer-Encoding: Chunked, which is somehow mangled by
mod_fastcgi. Varnish then claims the response is malformed and declines
to process it, sending the client a 503 instead.

This is a followup of 0ee9e717f49b9e15bd63fd66f3d0967939c35b05
