Imbed Server Name within HTML href

Question

My application is generating an email as a alert to an administrator to take some action.  I do not want to hard code the server name into the HTML href statement as depicted below
   -- Include link to HIR Admin page
   l_body_html :=
         l_body_html
      || '<a href="http://edwprd.dhhs.state.nh.us:7777/pls/oitp/f?p=222:469">Admin Items</a>';
I have been able to stuff the current url into a hidden item via an on load dynamic action using this javascript
<script type="text/JavaScript">
$s('P481_URL', window.location.href);
</script>
I then transform that hidden item in a pl/sql anonymous block process using this code and set local variable
SELECT
SUBSTR ( :p481_url,
1,
INSTR ( :p481_url,
1,
3))
|| '469'
  INTO v_sql
  FROM DUAL;
Which yields this string into the variable v_url
http://vmdhhsdworad:7777/pls/oitd/f?p=103:469
Is it possible to include that local variable into the href attribute?

Answer 1

APEX_UTIL.HOST_URL
Example
The following example demonstrates how to use the HOST_URL function to return the URL, including the script name, to the current Application Express instance.
declare
    l_host_url      varchar2(4000);
    l_url           varchar2(4000);
    l_application   varchar2(30) := 'f?p=100:1';
    l_email_body    varchar2(32000);
begin
    l_host_url := apex_util.host_url('SCRIPT');
    l_url := l_host_url||l_application;
    l_email_body := 'The URL to the application is: '||l_url;
end;
