Problem with double slashes in URL when using nginx as proxy

Server NGINX
#1

Hi all,

I have web server where nginx is using as proxy for PHP scripts and web
server for static files. I use the following configuration:

server {
listen 80;
server_name *******.com;
access_log /var/log/nginx/.com.access_log;
location ~
.(jpg|jpeg|gif|png|css|js|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|tar|wav|bmp|rtf|swf|ico|flv|txt|xml|docx|xlsx)(?.+)?$
{
root /var/www/.com/public/;
index index.html index.php;
expires max;
access_log off;
}
location ~ /.ht {
deny all;
}
location / {
proxy_pass http://127.0.0.1:8080/;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-for $remote_addr;
proxy_set_header Host $host;
proxy_connect_timeout 60;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_redirect off;
proxy_set_header Connection close;
proxy_pass_header Content-Type;
proxy_pass_header Content-Disposition;
proxy_pass_header Content-Length;
}
}

Also there is apache2 running on port 8080 and process all non static
requests.

The problem in following - when I request
/en/all/all/filtered/246/1/date///-1//0 in logs of apache I see:

...** - - [27/Jul/2010:12:33:48 +0000] “GET
/en/all/all/filtered/246/1/date/-1/0 HTTP/1.0” 200 11548 “-”
“Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.8)
Gecko/20100722 Firefox/3.6.8 GTB7.1”

Please notice that there is no double slashes already. Apache gets
“/en/all/all/filtered/246/1/date/-1/0” instead of requested
“/en/all/all/filtered/246/1/date///-1//0”. And it creates problems in
the code.

And when I request Apache directly with
:8080/en/all/all/filtered/246/1/date///-1//0 it just works Ok. So I
suppose double slashes are missed somewhere in nginx.

I have nginx/0.7.67 installed.

Any ideas will be appreciated. Thanks!

Strange,

When post is specified in listen directive:

server {
listen 80;
…
}

it works well with double slashes.

But when using domain name in listen directive

server {
listen *****.com;
…
}

it removes double slashes.

Sorry vice versa :slight_smile:

With domain name it works well. But when port is specified in listen it
removes double slashes.

You probably proxy using

location / {
    proxy_pass http://backend/;
}

You need ot remove the last “/”, then nginx will use a client original
request with double slashes:

location / {
    proxy_pass http://backend;
}

Igor,

I’ve already replaced it to proxy_pass http://127.0.0.1:8080; after your
first post.

And now when I change it to:

server {
listen 80;
…
}

It removes double slashes.

With domain name it works just well.

Thanks,
Alex
