I would have thought you could use a stream expression with a single token. Here is a more tested example with the unnecessary backreference in the regex removed: 

 
 when HTTP_RESPONSE {  
    
      Disable the stream filter by default  
     STREAM::disable  
    
      Check if response type is text  
     if {[HTTP::header value Content-Type] contains "text"}{  
    
         Match any http:// instance and replace it with nothing 
        STREAM::expression {@http://.*?example\.com@@} 
    
         Enable the stream filter for this response only  
        STREAM::enable  
     }  
  }   
  when STREAM_MATCHED {  
     log local0. "[IP::client_addr]:[TCP::local_port]: matched: [STREAM::match], replaced with: [string map {http:// https://} [STREAM::match]]"  
     STREAM::replace "[string map {http:// https://} [STREAM::match]]"  
    
  }

And the output:

Rule stream_expression_rule : 10.0.0.1:3413: matched: http://test.example.com, replaced with: https://test.example.com

Rule stream_expression_rule : 10.0.0.1:3413: matched: http://example.com, replaced with: https://example.com
