Updated new version that decrements argc appropriately. Verified that it
is correct in the remap case.

I wondered about that. But I would be concerned about the plugin firing
twice for the same transaction. Not to mention, what's the point of a remap
rule if it's already enabled for every transaction?

Don't you also need to adjust ``argc``?

It seems like the only reason I can't have this as a global and a
transaction plugin is the config is in globals. What do you think about moving
that into an instance config for the remap case?

GitHub user shinrich opened a pull request: https://github.com/apache/trafficserver/pull/ TS-4972: Configure collapsed_forwarding plugin as global or remap. Add the ability to configure collapsed_forwarding plugin globally. Original version can only be configured per remap. Also cleaned up a memory leak in the event of failed transaction. You can merge this pull request into a Git repository by running: $ git pull https://github.com/shinrich/trafficserver ts-4972 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/trafficserver/pull/.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes # commit 0bebc97d000e09058d4c8c28c085145c694c1973 Author: Susan Hinrichs Date: 2016-10-14T15:38:12Z TS-4972: Configure collapsed_forwarding plugin as global or remap. --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
