--- Comment #3 from Andrii Ustymenko <ustymenko.and...@gmail.com> --- Hi all, Have the same issue in 2.4.55. Apparently the code mentioned earlier :~$ vim mod_proxy_balancer.c [...] /* Ignore parameters if this looks like XSRF */ ref = apr_table_get(r->headers_in, "Referer"); if (apr_table_elts(params) && (!ref || !safe_referer(r, ref))) { ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, APLOGNO(10187) "ignoring params in balancer-manager cross-site access"); apr_table_clear(params); } [...] is checking for the Referer header in the request. The correct Referer can be taken from DevTools when accessing balancer-manager page in the browser and clicking on the corresponding backend. Adding that to the request will fix the issue. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: bugs-unsubscr...@httpd.apache.org For additional commands, e-mail: bugs-h...@httpd.apache.org
