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]"
    }
  }
}

Hi Mohamed,

Thanks for your reply. Here is the example. I'm using this to test. In the real scenario, the header name "{esbsoaheader}userName" was already found in the HTTP headers, but in this test scenario and I'm adding it and then trying to remove it. I'm not sure how it worked for you.

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]"
}
}

}

LOGS

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""

Hi Mohamed
This is my set up. The version is 16.1.3
It is very strange that it works for you but not for me... Am I missing something here?
