Set Variable from Content of Text File?

[Resicow]

Hi Nick,

Thanks for your response... I understand the response below, but I was 
hoping for a way of doing this by reading the contents of the text 
file... So something like this...

    if (-f $document_root/system/back_soon.txt) {

            set $file_to_load read /$document_root/system/back_soon.txt
            rewrite  ^(.*)$  $file_to_load last;
            break;

}

So if the file exists read and set a variable based on the contents of 
the file, and then rewrite to the variable path.

Thanks,

John
