Hi Gang
We use a mysql database to store call forwarding information for customers.
To reduce the amount of mysql queries from the config, we use an expiring htable to cache this information.
This has the drawback that if a customer alters his call forwarding settings this might not be immediately active as long as old data is still cached in the htable.
To avoid this I am looking for a way to remove cached data when a customer calls a service number.
jsonrpc_exec() calling htable.delete on the key works.
We have a pair of redundant servers so I would need to also delete the key on another server via RPC HTTP request.
How can I perform an jsonrpc call via HTTP to a remote server?
Mit freundlichen Grüssen

take a look at JSONRPC and xHTTP.
There is a nice article by Ben Kaufmann in at Kamailio RPC over HTTP Introduction | kaufmania https://kaufmania.wordpress.com/2023/09/10/kamailio-rpc-over-http-introduction/ explaining. (i have this URL in my Favorites list, not sure if it is still available)

Hello,
you can use one of the json modules to create the JSON request and then use http_client or http_async_client module, the usual way.
Cheers,
Henning
