Help deleting header name that contains curly braces

Hi

Just a quick question.  I was asked to use the F5 to remove a header name as follows {esbsoapheader}userName

The header value was just fine.  But I was asked to remove {esbsoapheader} from header name  {esbsoapheader}userName

I tried HTTP::header remove "{esbsoapheader}userName"   but it did not work.  I got an error as follows 

TCL error: /Common/ilxpi_demo/ilxir_demo <HTTP_REQUEST> - list element in braces followed by "userName" instead of space while executing "HTTP::header remove "{esbsoapheader}userName""

I'm guessing the header name has invalid characters, ie "{}"  Has anyone encountered something similar?  Is this header name ilegal/malformed? Is there a way I can remove this?

 

Any help is appreciated! thank you!

    I think I just figured it out guys Mohamed_Ahmed_Kansoh  CA_Valli 

    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.

    when HTTP_REQUEST {
  if { [HTTP::uri] eq "/demo2" } {
    HTTP::header insert "{esbsoapheader}userName" "spencer"
    foreach aHeader [HTTP::header names] {
      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]"
    }
  }
}
