Hi all:

I’m trying to print a report with product ean13 barcodes and the  
barcodes are printed blank.

I think my problem is an incorrect redirection problem because I can see  
correctly the barcodes if I browse to the url:

[https://mydomain.net/report/barcode/?type=EAN13&value=8435095319553&width=300&height=300&humanreadable=1](https://mydomain.net/report/barcode/?type=EAN13&value=8435095319553&width=300&height=300&humanreadable=1)

MY server response in that case is:

"GET  
/report/barcode/?type=EAN13&value=8435095319553&width=300&height=300&humanreadable=1

HTTP/1.0" 200 -

But if I try to print the report with barcodes my server response is:

"GET  
/report/barcode/?type=EAN13&value=8435095319508&width=600&height=200&humanreadable=1

HTTP/1.0" 302 -  
"GET  
/?redirect=http%3A%2F%[2Fmydomain.com](http://2Fmydomain.com)%2Freport%2Fbarcode%2F%3Ftype%3DEAN13%26value%3D8435095319508%26width%3D600%26height%3D200%26humanreadable%3D1

HTTP/1.0" 302 -

My nginx configuration file:

upstream openerpweb {

}

server {  
listen 80;

```

```
      # set headers

      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;

              proxy_read_timeout 600;
              send_timeout 600;

      # Let the OpenERP web service know that we're using HTTPS,

```

otherwise  
# it will generate URL using http:// and not https://  
proxy\_set\_header X-Forwarded-Proto https;

```
      # by default, do not forward anything
      proxy_redirect off;
  }

  # cache some static data in memory for 60mins.
  # under heavy load this should relieve stress on the OpenERP web

```

interface a bit.  
location ~\* /web/static/ {  
proxy\_cache\_valid 200 60m;  
proxy\_buffering on;  
expires 864000;  
proxy\_pass [http://openerpweb](http://openerpweb);  
}

}

Any idea?

Thanks a lot.
