CFHTTP & URL error

[aleci]

Hi all,
I am working on retrieving news content from the 'Guardian-Unlimited' site.

If the URL doesnt work through technical problems,i want to be able to abort the retrieval and display previous news already stored in a DB instead.

Can CFHTTP 'test' the given URL prior to executing the retrieval??

My code is as follows:

<!--deletes previously stored news-->
<cfquery name=&quot;delete_all_records&quot; datasource=&quot;guardian&quot; dbtype=&quot;ODBC&quot;>
DELETE FROM news
</cfquery>

<!--Retrieval-->
<cfhttp method=&quot;get&quot;
url=&quot;

http://www.guardian.co.uk/Distribution/Artifact_Trail_Block/0,5184,179200-0-10,00.html&quot;

path=&quot;C:\My Documents\Alexis\Guardian\&quot; file=&quot;guardian.txt&quot;>

<CFFILE ACTION=&quot;Read&quot; FILE=&quot;C:\My Documents\Alexis\Guardian\guardian.txt&quot; VARIABLE=&quot;news&quot;>

<CFOUTPUT>
#news#
</CFOUTPUT>

thanks in advance for any help

If you add &quot;ThrownOnError to your CFHTTP tag (I also added a timeout of 5 seconds) then you can use CFTRY/CFCATCH


<CFSET vDelete = Yes>

<CFTRY>

<!--Retrieval-->
<cfhttp method=&quot;get&quot;
url=&quot;

http://www.guardian.co.uk/Distribution/Artifact_Trail_Block/0,5184,179200-0-10,00.html&quot;;

path=&quot;C:\My Documents\Alexis\Guardian\&quot; file=&quot;guardian.txt&quot; TIMEOUT=&quot;5&quot; THROWONERROR=&quot;Yes&quot;>

<CFCATCH TYPE=&quot;Any&quot;>
Could Not Find File
<CFSET vDelete = No>
</CFCATCH>

</CFTRY>

<CFIF vDelete>
<!--deletes previously stored news-->
<cfquery name=&quot;delete_all_records&quot; datasource=&quot;guardian&quot; dbtype=&quot;ODBC&quot;>
DELETE FROM news
</cfquery>

<CFFILE ACTION=&quot;Read&quot; FILE=&quot;C:\My Documents\Alexis\Guardian\guardian.txt&quot; VARIABLE=&quot;news&quot;>

<CFOUTPUT>
#news#
</CFOUTPUT>

<CFELSE>
<!--deletes previously stored news-->
<cfquery name=&quot;qNews&quot; datasource=&quot;guardian&quot; dbtype=&quot;ODBC&quot;>
SELECT * FROM news
</cfquery>

<CFOUTPUT QUERY=&quot;qNews&quot;>
#news#
</CFOUTPUT>
</CFIF>
