Question

abort a failed process inside a .cfm page

Hello everyone,
I have been bothered by this for a while.
I have a cfm page that is doing a process of extracting data and ftp to locationA. I have this running for about two years. Then there came the need to do the same process and ftp to locationB. I did not want to repeat the process, so I added ftp locationB at the end of the program, to use the same data file
The process runs well all the time when I only had LocationA. The problem is locationB ftp server sometimes would close and not to let me connect. this would stall the whole process (I gues it was a rollback feature in cold fusion?), including the steps of ftp to locationA, even though locationA's connection was fine and open.
Is there a way in Cold fusion pages to abandon a step that fails? In this case, I can put the code to ftp locationB in a template. If this template fail, go on to the the next line in the main page and not to quit the whole thing? I have seen this in other programming languages which have the "abort" function.

Thanks in advance,

    You can always catch "any" exception thrown.
    <cftry>
    <cfftp action = "putfile"
    username = "anonymous"
    password = "mypassword"
    server = "clientserver"
    localFile = "c:/#filename#.xml"
    remoteFile = "/uploads/#filename#.xml"
    >
    <cfcatch type="any">
    <!--- do your thing here! --->
    <cfdump var="#cfcatch#" />
    </cfcatch>
    </cftry>

    I figured it out!
    Here is the code:
    <cftry>
    <cfftp action = "putfile"
    username = "anonymous"
    password = "mypassword"
    server = "clientserver"
    localFile = "c:/#filename#.xml"
    remoteFile = "/uploads/#filename#.xml"
    >
    <!--- <p>... other processing goes here --->
    <!--- specify the type of error for which we search --->
    <cfcatch type = "application">
    <!--- the message to display --->
    <h3>You've Thrown a Application <b>Error</b></h3>
    <cfoutput>
    <!--- and the diagnostic message from the ColdFusion server --->
    <p>#cfcatch.message#</p>
    <p>Caught an exception, type = #CFCATCH.TYPE# </p>

    </cfoutput>
    </cfcatch>
    </cftry>

    All I care is that the program does not stop because of the ftp error. I don't need the detail error message. Once I took out the lines in the example, it worked fine.

    Thank you for your suggestions.
    I read the Help section for cftry and cfcatch. the example given is for a database query error. When I replace it with the type with "application", the cftry and cfcatch did not work. It throw me the "ugly" message and stopped.
    Here is the code that I would like to abort:

    <cfftp action = "putfile"
    username = "anonymous"
    password = "mypassword"
    server = "clientserver"
    localFile = "c:/#filename#.xml"
    remoteFile = "/uploads/#filename#.xml"
    >

    How should I define the cfcatch type here for an ftp process?

    Thanks!
