CFHTTP Error Trapping

I have a CFHTTP reference in a template and it occured to me that if the other server is down, it may bring a whole site down.

How do I trap for the possibility that <CFHTTP url=" http://2XX.1XX.88.1XX/listindex.php" method="GET"
resolveurl="No"></CFHTTP> cannot be read?

I canot afford to experiment with CFTRY and CFCATCH on this live site so exact code would be appreciated.

Thanks!

    Hi IraMSN,
    For testing purposes, if you can't use another machine or a local copy of the cfm file, you might at least create a copy of the file and then modify it for testing. I say this without know what you're environment looks like that.

    Anyway, you might try adding the 'timeout' param to limit your exposure to the other site being down.

    there are some discussions on this page that talk about some general instability in the cfhttp tag... there are also some related blog posts at the bottom of it:

    hope it helps.

    Hi Sagewire,

    Thank you for the reply and calling the docs to my attention <g>.

    Unfortunately we need to use CFHTTP to read some info from a JavaScript api. By using TIMEOUT =1 in CFHTTP, it displays a "Connection Timeout" in the table cell if there is no connection which is acceptable. It doesn't bring down the site. It is a chat application and if the chat server goes down for a little while, it's not critical to other site features.

    Thanks again!
