-+    32bit vs 64bit system) allowing for XML escaping within the bounds of

-+    and is not recommended since it does not account for memory consumed

-From ced24e032ebe185a2d885fa309d6de47668ba31e Mon Sep 17 00:00:00 2001
-From: Yann Ylavic <ylavic@apache.org>
-Date: Fri, 26 Jun 2020 10:21:19 +0000
-Subject: [PATCH] Merge r1878280 from trunk:
-
-mod_proxy_http: don't strip EOS when spooling request body to file.
-
-To prevent stream_reqbody() from sending the FILE and FLUSH bucket in separate
-brigades, and thus apr_file_setaside() to trigger if network congestion occurs
-with the backend, restore the EOS in spool_reqbody_cl() which was stripped
-when spooling the request body to a file.
-
-Until APR r1878279 is released (and installed by users), apr_file_setaside()
-on a temporary file (mktemp) will simply drop the file cleanup, leaking the
-fd and inode..
-
-This fixes BZ 64452.
