Check to see if a page exists?

[jeby]

Is there a way that I can check to see if a page exists? I was thinking it
might be possible with CFHTTP or something along those lines but am not sure.

I am working on a web app and there is a part where it creates a path base on
a string and I need to be able to verify if the path is valid so that i can
redirect is as appropriate if it is not.

Please Help!!!

Hi Josh,

CFHTTP will do what you want, just check CFHTTP.errorDetail or
CFHTTP.responseHeader.status_code after the call. BUT, if this is a path to
a file on the local file system, you can also use CFDIRECTORY or CFFILE (if
you know a file that is sure to be in the path). Just some ideas.

HTH and good luck!

is that an internal or external page?

[flasheister]

I'm gonna give this a try, i need to loop through hundreds of URLs automatically...any suggestions on when to timeout and move to the next site or how to error check it?

in response to chris....

So, If i do CFHTTP and get no error then it exists?

in respons to jorgepino...

It is an internal page. I am writing an application that creates a file path
from a string that is passed in the URL. I want to be able to forward the page
to a default path if the page the string points to does not exist...

I dont know if this will be of any extra help to anyone.

My other idea is so possibly catch the error with a <CFTRY> and a <CFCATCH>
but I do not know how to use that tag and have been fairly unsuccessful with it
in the past. If someone could tell me if it would work and how to do it i
would appreciate it.

Thanks everyone! All suggestions are helpful!

If these are all local pages and I understand what you're getting at,
you could use FileExists() to check for the existence of the file.

quickest way for an internal file is :

<cfdirectory action="list" filter="#fileName#" directory="#filePath#"
name="checkFile">
<cfif checkFile.recordcount neq 0>
FileExists
<cfelse>
No File, YOU LOSE!
</cfif>

FileExists(ExpandPath(yourfile)) Boolean yes or no

<cfif FileExists(ExpandPath(yourfile))>
<p>Your file exists in this directory. You entered
the correct file name, #GetFileFromPath("#thisPath#/#yourfile#")#
<cfelse>
file not found
</cfif>
