Nginx redirection problem in odoo

[cubells]

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

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%2Freport%2Fbarcode%2F%3Ftype%3DEAN13%26value%3D8435095319508%26width%3D600%26height%3D200%26humanreadable%3D1 

HTTP/1.0" 302 -


My nginx configuration file:

          # by default, do not forward anything

      }

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

      location ~* /web/static/ {
          proxy_cache_valid 200 60m;
          proxy_buffering    on;
          expires 864000;
          proxy_pass http://openerpweb;
      }

}


Any idea?

Thanks a lot.
