You could use the CFHTTP tag along with the TIMEOUT and THROWONERROR
attributes. Something like this:
<CFSET TIMEOUT_PERIOD = ""> <!--- # seconds to wait on a response --->
<CFSET URLS_TO_TRY_LIST = ""> <!--- List of URLs to attempt to contact --->
<CFSET URL_AVAILABLE = FALSE> <!--- Flag for availability of the URL --->
<CFLOOP INDEX="URL_TO_TRY" LIST="#URLS_TO_TRY_LIST#>
<CFTRY>
<CFHTTP
URL="#URL_TO_TRY#"
METHOD="GET"
TIMEOUT="#TIMEOUT_PERIOD#"
THROWONERROR="yes">
<CFSET URL_AVAILABLE = TRUE>
<CFBREAK>
<CFCATCH>
<!--- CHECK WHATEVER CFHTTP.* VALUES NEEDED AND CONTINUE (OR
NOT) --->
</CFCATCH>
</CFTRY>
</CFLOOP>
<CFIF URL_AVAILABLE><!--- DO WHATEVER --->
Caveats: If you have to do multiple transactions, there's no guarantee that
a given URL won't become unavailable in between the time that you check and
the time you actually try to do something else. Also, processing on the
other web server after the timeout won't necessarily cease when ColdFusion
on your end does, so you have to be careful about things like database
changes (updates/inserts/deletes).
Hope this helps...
