Hello,<br>
<br>
you can use:<br>
<br>
if(is_present_hf("aaa")) ...<br>
<br>
Also, it should work like:<br>
<br>
if($hdr("aaa") != $null) ...<br>
<br>
The is_present_hf() should be slightly faster as it just walks
through the list of headers, not parsing the header body and not
returning its value.<br>
<br>
Cheers,<br>
Daniel<br>
