    Paste this and run it.  It worked out for me.  Now any of you can explain why this works??  Is this a bug with F5?  At least it seems to me.  If it is, how can I let them know so they can fix it.

  if { [HTTP::uri] eq "/demo2" } {
    HTTP::header insert "{esbsoapheader}userName" "spencer"

      log local0. "HTTP Request Headers: $aHeader: [HTTP::header value $aHeader]"

    log local0. "***************REMOVING BAD HEADER************"
    HTTP::header remove "\\{esbsoapheader\\}userName"
    foreach aHeader [HTTP::header names] {
      log local0. "HTTP Request Headers: $aHeader: [HTTP::header value $aHeader]"
    }
  }
}

Spencer_Aranda , 

It doesn’t make sense , but I will add it to my Notes. 
I do not know why it works after " \\ \\ " it’s strange !!

    Thanks Mohamed_Ahmed_Kansoh 

    Hopefully in the future you can let me know how/why this works the way it does.  And hopefully this can get fixed.
