You're seeing this error because multiple "HTTP::redirect" or "HTTP::response" are being triggered per single request. No more than one redirect statement can function per request. You should not ignore that, and fix the iRules with a proper use of "event disable" function.

To get rid of this error, use the "event disable" command after invoking your redirect. Below is one sample how you can use it.

iRule1

when HTTP_REQUEST {
 if { ([HTTP::host] == "asd.asd.asd") && ([HTTP::path] == "/") } {
   HTTP::respond 302 location "https://[HTTP::host][HTTP::uri]"
   event disable  The HTTP response event in second iRule is not processed
   TCP::close  The connection record is removed
 }
}

iRule2

when HTTP_REQUEST {
 if { ([HTTP::host] == "asd.asd.asd") && ([HTTP::path] == "/products") } {
   HTTP::respond 302 location "http://foo.bar/products"
   event disable  Not required here, but still recommended
   TCP::close
 }
}

Hi Hannes, This is one of the virtual which has redirect iRule assigned ltm virtual vs_test { destination 151.142.X.X:http ip-protocol tcp mask 255.255.255.255 profiles { PR_HTTP_XFF_Enabled_http { } tcp { } } rules { _sys_https_redirect } source 0.0.0.0/0 source-address-translation { type automap } vs-index 95 } This is the default irule: _sys_https_redirect when HTTP_REQUEST { HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri] } Thanks, Sekhar
