<p class=MsoNormal style='text-align:justify'><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal style='text-align:justify'><span lang=EN-GB>I have tried to
raise an asynchronous request to a webpage using XMLHttpRequest(); and also
YAHOO.util.Connect.asyncRequest; but both requests are being caught by this exception
:
try{(this.options['on'+event]||OpenLayers.Ajax.emptyFunction)(transport,json);OpenLayers.Ajax.Responders.dispatch('on'+event,this,transport,json);}catch(e){this.dispatchException(e);}<o:p></o:p></span></p>

<p class=MsoNormal style='text-align:justify'><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal style='text-align:justify'><span lang=EN-GB>It is quite
strange that none of the two requests are passing through, and I also tried to
use OpenLayers.loadURL to give me the same exception.<o:p></o:p></span></p>
<p class=MsoNormal style='text-align:justify'><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal style='text-align:justify'><span lang=EN-GB>Any help how I
can fix this problem is extremely appreciated.<o:p></o:p></span></p>
<p class=MsoNormal style='text-align:justify'><span lang=EN-GB><o:p> </o:p></span></p>
<p class=MsoNormal style='text-align:justify'><span lang=EN-GB>Below please
find the three different methods I tried to get the 2<sup>nd</sup> PHP working.
(Please note that I already have a loadURL being used for routing and it works
perfectly!)<o:p></o:p></span></p>
