Error Rules

These rules mask application exceptions and errors with custom pages.

Overview​

Error Rules is a feature of Haltdos DDOS that allows application owners to show custom pages without revealing internal exceptions generated by the application upon failure. The custom pages can be created for specific HTTP error codes respectively and thus be used with the error rules.

Note

This feature will only appear when client license has SSL offloading enabled.
