Hi Valentin, > > http://nginx.org/en/docs/http/ngx_http_core_module.html#variables > > $cookie_abc_cnv1, $cookie_abc_cnv2, $cookie_abc_cnv1... Ah. I did know how to read it individually. My mistake, should have explained it more clearly. But testing for each of this variables looks bad (is ther a way other than using a if clause ? ) Thanks Harish
