[Tilecache] Max-Age

[Alexandre Dube]

Hi Linde,

# in Service.py :
...........
        if "HTTP_X_FORWARDED_HOST" in os.environ:
            host      = "http://" + os.environ["HTTP_X_FORWARDED_HOST"]
        elif "HTTP_HOST" in os.environ:
            host      = "http://" + os.environ["HTTP_HOST"]

        host += os.environ["SCRIPT_NAME"]
        req_method = os.environ["REQUEST_METHOD"]
        format, image = service.dispatchRequest( params, path_info, 
req_method, host )
        print "Cache-Control: public, max-age=604800" # <----------------
        print "Content-type: %s\n" % format

        if sys.platform == "win32":
            binaryPrint(image)
        else:
            print image
    except TileCacheException, E:
        print "Cache-Control: max-age=10, must-revalidate" # make the 
client reload
        print "Content-type: text/plain\n"
        print "An error occurred: %s\n" % (str(E))
..............

Best regards,

Alexandre
