Connecting real web content to RAG/Agents — a few proxy-related lessons learned the h

[Cecilia]

[font=宋体]Been building a RAG pipeline that needs fresh web pages in real time. Turns out the model isn’t the biggest bottleneck — the real choke point is how to reliably get clean, unblocked public content.[/font]

[font=宋体]Started with datacenter IPs and got blocked by various protections pretty quickly. Switching to residential proxies helped a lot — real user IPs are definitely more friendly toward Cloudflare and similar systems. Currently using Helodata (they have both residential and mobile). Supports multi-country switching, and it works with standard protocols so you can plug it straight into LangChain and similar frameworks without custom adapters.

[font=宋体]The pool feels decent, and you can control rotation as well as sticky sessions. But honestly, when you run high concurrency for a long time you still need to keep an eye on the success rate yourself — you can’t just set it and forget it.[/font]

[font=宋体]Anyone else working on AI data pipelines or autonomous agent browsing? How are you solving the “real internet perspective” problem right now? Any solid combinations (proxy + fingerprinting + retry logic) that actually work? Looking for real experiences, not just product names.[/font]
