# Clients like xDavv5 on Android, or Cyberduck, use chunked requests.
# When FastCGI or FPM is used with apache, requests arrive to Nextcloud without any content.
# This leads to the creation of empty files.
# The following directive will force the problematic requests to be buffered before being forwarded to Nextcloud.
# This way, the "Transfer-Encoding" header is removed, the "Content-Length" header is set, and the request content is proxied to Nextcloud.
# Here are more information about the issue:
#  - https://docs.cyberduck.io/mountainduck/issues/fastcgi/
#  - https://docs.nextcloud.com/server/latest/admin_manual/issues/general_troubleshooting.html#troubleshooting-webdav

# Apache disabled the sending of the server-side content-length header
# in their 2.4.59 patch updated which breaks some use-cases in Nextcloud.
# Setting ap_trust_cgilike_cl allows to bring back the usual behaviour.
# See https://bz.apache.org/bugzilla/show_bug.cgi?id=68973
