    In addition to what Paulius says, you can try the iRule below.

    when HTTP_REQUEST {
        # Disable the stream filter by default   
        STREAM::disable 
     
        # LTM does not uncompress response content, so if the server has compression enabled
        # and it cannot be disabled on the server, we can prevent the server from
        # sending a compressed response by removing the compression offerings from the client
        HTTP::header remove "Accept-Encoding"
        
        if { [HTTP::uri] starts_with "/f5/anchor_link_redirect" } {
            set href [b64decode [URI::query [HTTP::uri] href]]
            if { $href equals "https://support.abc.int/supportnet/application.jsp#support/32" } {
                HTTP::redirect "https://pxl.saas.supportsystems.com/assystnet/application.jsp#services/48"
            }
            else {
                HTTP::redirect $href
            }
        }
    }
    	
    when HTTP_RESPONSE {
        if { ([HTTP::header "Content-Type"] starts_with "text/html") } { 
            STREAM::expression {@</title>@</title>
        <script>
        document.addEventListener(`click`, e => {
          const origin = e.target.closest(`a`);
    
          if (origin && origin.href.indexOf('#') > -1) {
            const base64_href = btoa(origin.href);
            window.location.href = '/f5/anchor_link_redirect?href=' + base64_href;
          }
        });
        </script>@}
            STREAM::enable
        }
    }
