   if { [HTTP::host] contains ":" } {

We're running v12.1.4. It only happens every so often so I don't actually know what is causing it. I did wonder if it was something to do with the string replacement. I prefersetting a varaible before the replacement so I'll do that and see if it stops it.

 

Thanks for your answers.
