From 488a214a81a25c6397c56822ed1713f51dddc520 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Thu, 19 Feb 2009 22:38:36 +0100 Subject: Add support for ETag in 'plain' view When downloading a blob identified by its path, the client might want to know if the blob has been modified since a previous download of the same path. To this end, an ETag containing the blob SHA1 seems to be ideal. Todo: add support for HEAD requests...
