From 0715f7e19b4f7e7b423f1fb3a8348fbc85bb82fb Mon Sep 17 00:00:00 2001 From: Felix S Date: Wed, 11 Aug 2021 15:39:17 +0000 Subject: [PATCH] Revert erroneous use of the `Content-Length` header (#637) This reverts commit 6c907eb33ffd79ef9c4761c6460acb31b2eded46 The use of the Content-Length value here is erroneous and may lead to truncated downloads if a compression scheme is specified in the Content-Encoding header, as the Content-Length header refers to the size of encoded data, not of the raw bytestream. This has been noticed in the wild with WebVTT subtitle segments.
