Hi,
it also works on Apache :
Webdav works fine while fastcgi mode is set to false and the Apache vhost use Proxypass
Change
# FASTCGI
RewriteCond %{HTTP:Authorization} (.+)
RewriteRule ^(/davf.*)$ /seafdav.fcgi$1 [QSA,L,e=HTTP_AUTHORIZATION:%1]
RewriteRule ^(/davf.*)$ /seafdav.fcgi$1 [QSA,L]
to this
# WCGI / PROXY
SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1
ProxyPass /davf http://127.0.0.1:8080/
ProxyPassReverse /davf http://127.0.0.1:8080/
