Project Highlights The idempotent-proxy is a reverse proxy service written in Rust with built-in idempotency support. This project addresses the need for consistent and reliable request handling by caching responses to repeated requests with the same idempotency key. The target users are developers …

There is no longer a need to use the Idempotent Proxy, as ic-cdk v0.19.0 has already resolved this issue. [image] Announcing Two Major Upgrades for HTTPS Outcalls: IPv4 Support + Non-Replicated Calls are now LIVE! Developers Hello everyone, We’re thrilled to …

:wave: @zensh First I’d like to thank you for the awesome work you did with the idempotent-proxy. It’s been a month we are using it and it works very well. One thing we would like to do though is to reduce the number of cycles it consumes. It currently consumes almost 1T cycle/day. I have been tryi…

[image] sardariuss: proxy_token The proxy_token request is infrequent, and its cycles consumption is negligible. The main source of cycles usage is the HTTP Outcall, which depends on your business needs. To reduce cycles consumption, you can: Minimize HTTP calls. Reduce the size of request …

Thanks for your answer. This is surprising to me, because my app has currently almost no user, so most of the time there is not a single http outcall made. However, the burn rate is very stable as you can see: [image]

You can find details about signature costs at Threshold signatures | Internet Computer . A simple calculation: Using test_key_1, each signature costs 0.01 T. With a single proxy agent refreshing the signature hourly, the daily cycles consumption is: 24 * 0.01 T = 0.24 T. Including business-relate…

@zensh Considering that replicated HTTP outcalls ensure that a single node cannot manipulate the data, doesn’t introducing a proxy make the system less secure by requiring all parties to trust it? Is there a way for a canister to verify that the proxy has not altered the data?

This is not the responsibility of a proxy server.

I disagree, but thanks for the answer.

Hello! Very nice project! Is it still running?

Hi @zensh . Is this project and path still ongoing? Has anything changed in the meantime? I feel this is, on the one hand a feature of ICP but it does seem to block many use cases. Having a centralized proxy kind of defeats the entire purpose. I mean, for example I want to build a proof of concept …
