使用Nginx通过https方式访问SVN服务器，执行svn copy的时候出现以下错误：

（废话不多说，下面看解决办法）
svn: Server sent unexpected return value (502 Bad Gateway) in response to COPY request for

解决办法：

location / {
proxy_redirect    off;
proxy_set_header  Host $host;
proxy_set_header  X-Forwarded-Host $host;
proxy_set_header  X-Forwarded-Server $host;
proxy_set_header  X-Real-IP        $remote_addr;
proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
proxy_buffering    on;

set $fixed_destination $http_destination;
if ( $http_destination ~* ^https(.*)$ ) {
set $fixed_destination http$1;
}
proxy_set_header Destination $fixed_destination;

proxy_pass        http://127.0.0.1:8080;
}

主要是增加了

set $fixed_destination $http_destination;
if ( $http_destination ~* ^https(.*)$ ) {
set $fixed_destination http$1;
}
