Irule giving error : Operation not supported. Multiple redirect/respond invocations not allowed

Hi All,

Below is the url i have used in virtual server and i am getting error as below. Need some advice to make sure if we can write same irule in different way or how can we rectify these error.

TCL error: /Common/web-zwcom-http-irule - Operation not supported. Multiple redirect/respond invocations not allowed (line 18) invoked from within "HTTP::redirect "https://[HTTP::host][HTTP::uri]"" ("/en-/" arm line 2) invoked from within "switch -glob [string tolower [HTTP::uri]] { "/en/" - "/content/" - "/apps/" - "/etc/" - "/qr/" - "/libs/" - "/bin/*" - ..."

Code
when HTTP_REQUEST {
