For folks in the networking space, differentiating between L4 and L7 proxies is pretty important. And while you could call it an HTTP proxy in many circumstances, some proxies support other protocols e.g a mysql proxy.
- lttlrck 2y agoYes, IMHO calling it a Layer 7 proxy it quite misleading. I was expecting something closer to an ALG.
- gtirloni 2y agoCalling a reverse HTTP proxy a Layer 7 proxy is misleading? Why?
- molszanski 2y agoProbably because OSI never materialized IRL and today they are all mixed up left and right and not how we “designed” and “imagined” it 50 years ago
- allynb 2y agoI think it's only misleading in that the only L7 protocol it supports is HTTP. It's not a huge deal, but when I work with other proxies if I see L7, I assume multiple application protocols.
- thayne 2y agoIn my opinion "application layer" and "transport layer" would be better terms than L7 and L4.
- Karrot_Kream 2y agoIn my last role I started trying to enforce this by refusing to use the terms "Layer 7" and "Layer 4" (I worked on application and transport layer infrastructure at a big tech) but it never caught on and after having to give "the talk" about what happened to OSI Layers a few times I resigned myself to the fate that it was never happening. I will continue to use those terms though.
