Webmaster Forum / ColdFusion / Advanced Techniques / May 2008CFHTTP - verify file first
I am currently retrieveing files from another server via cfhttp. Occasionally, the files get renamed and my script throws an error. How can I verify if a file exists on a remote server before I make the cfhttp connection? check the statuscode returned in the cfhttp structure: 200 means file is there. Azadi Saryev Sabai-dee.com http://www.sabai-dee.com/ I had to deal with the same problem about a week ago. Here's how I got around it: <cftry> <cfhttp method="head" name="testTheFile" url="myurl.html"></cfhttp> <!--- If code reaches this point, File Exists ---> <cfcatch> <!--- File does not exist ---> </cfcatch> </cftry> |
