    Could you add the follow irule to the virtual server?

    when HTTP_REQUEST {
   # Disable the stream filter for client requests
   STREAM::disable
}
when HTTP_RESPONSE {
    # Disable the stream filter for server responses
    STREAM::disable
# Enable the stream filter for text responses only

 if {([HTTP::status] == 200) && ([HTTP::header value Content-Type] starts_with "text")} {
  # Replace '10.100.100.200' with '10.200.6.1'
  STREAM::expression {@10.100.100.200@10.200.6.1@}
  # Enable the stream filter
  STREAM::enable
 }
}

Thank you so much.

I resolved the issue using your answer's iRule.

Your welcome.
But be aware, this will only work if you access the website on IP address.
This irule will work if you access the website on DNS name.

 

 

 

when HTTP_REQUEST {
   # Disable the stream filter for client requests
   set orig_host [HTTP::host]
   STREAM::disable
}
when HTTP_RESPONSE {
    # Disable the stream filter for server responses
    STREAM::disable
# Enable the stream filter for text responses only

 if {([HTTP::status] == 200) && ([HTTP::header value Content-Type] starts_with "text")} {
  # Replace '10.100.100.200' with 'host header'
  STREAM::expression {@10.100.100.200@$orig_host@}
  # Enable the stream filter
  STREAM::enable
 }
}
