Capture requests

[Juan Ignacio Garzón]

Hi,
I need to capture the requests sent by strophe, as I need to modify some trivial things on the auth stanzas that are sent on the initial requests.

I tryied to use a custom plugin and a handler. But none of these seem to work to process sent messages, they work fine for capturing received messages.
How would be the right procedure to do this?

Thanks!
