OK, I found the "CONFIG proxy.config.plugin.dynamic_reload_mode INT 0" to disable this new feature. After I already modified my plugin ... :-)

Hi, I have a plugin under ATS 7.1.x that performed initialization under the global plugin context. This initialized data used to be available to the remap contexts of the same plugin. I assume that the new remap plugin reloading capability in 9.0.0 means that this no long works (since remap plugins are considered different DSO files due to the copying to the unique directories)? Thanks, Peter
