Blacklisting with iRule + iControl

You are correct that the file upload command will not signal a reload of the configuration. You'll have to make one more call to tell the configuration to reload the file. Once you have reloaded the file, just use the LocalLB::Class::set_external_file_name() method with the existing file name. This will signal the internal system to reload the contents of the file.

 

 

As for your question about syncing the files, I'll have to check on that one for you and let you know.

 

 

Here's some perl code that I used to verify the reloading of the class. Hope it helps.
