Hi,
i want to use Nginx with apache2 and mod_dav_svn for hosting my SVN
Repository via https.
But i have problems on commit large files.
On a 8MB ffmpeg binary commit, my SVN client brings this error:
Commit failed (details follow):
Server sent unexpected return value (413 Request Entity Too Large) in
response to PUT request for
‘/svn/repo1/!svn/wrk/b2f0560a-05fd-427c-9039-d47dea9ff9c4/path/ffmpeg’
The Nginx error log says:
2013/02/05 14:20:25 [error] 22931#0: *2693 client intended to send too
large body: 8309431 bytes, client: 93.220.123.123, server: mydomain.com,
request: “PUT
/svn/repo1/!svn/wrk/b2f0560a-05fd-427c-9039-ababea9ff9c4/path/ffmpeg
HTTP/1.1”, host: “mydomain.com”
And nothing about the request in the apache logs.
So i think the nginx blocks the request, not the proxy to apache.
The Requests to the Nginx goes over HTTPS:
https://public-domain.com/svn/ (nginx) <> routing to
http://localhost:8080 (apache2)
My Nginx config already has client_max_body_size 256M; in the nginx.conf
inside http { } and server { } in the vost site config.
But it does not helps or is ignored.
i have searched all other nginx configfiles for “client_max_body_size”
without succes:
#> grep -R ‘client_max_body_size’ ./*
./nginx.conf: client_max_body_size 256M;
./sites-available/443_mydomain.com: client_max_body_size 256M;
./sites-available/443_mydomain.com: client_max_body_size 256M;
./sites-enabled/443_mydomain.com: client_max_body_size 256M;
./sites-enabled/443_mydomain.com: client_max_body_size 256M;
my site config file:
server {
listen 443;
server_name mydomain.com;
client_max_body_size 256M;
ssl on;
ssl_certificate
/path/ssl-cert/nginx/mydomain.com.2013-01.cacert.crt;
ssl_certificate_key /path/ssl-cert/nginx/mydomain.com.2013-01.key;
access_log /path/logs/nginx.https.mydomain.com.access.log;
error_log /path/logs/nginx.https.mydomain.com.error.log debug;
root /path/htdocs/mydomain.com;
index index.php index.html;
location / {
try_files $uri $uri/ /index.php;
}
location /svn {
client_max_body_size 256M;
keepalive_timeout 60;
include /etc/nginx/proxy_params;
proxy_pass http://127.0.0.1:8080;
set $dest $http_destination;
if ($http_destination ~ “^https://(.+)”) {
set $dest http://$1;
}
proxy_set_header Destination $dest;
}
}
So, what can i check?
What is wrong in my config?
Why is client_max_body_size ignored?
Does client_max_body_size not work on https?
Does client_max_body_size not work on PUT requests?
After 2 days of testing i hav no idea that to check. 
best regards,
Daniel.
