VCL Pipe heads up


Just as a heads up when you’re writing your own VCL, we don’t allow vcl_pipe in customer uploaded VCL.

The reason why: vcl_pipe opens a raw TCP socket in the network, and that’s not ideal when building a high scale CDN :smile:

The good news is that we’ve gotten really good at helping customers achieve their intended goals without using vcl_pipe – let us know what you’re using pipe for now, and we can help implement the logic in some other way.


We are trying to use without success. What is your suggestion to support this without vcl_pipe?


Unfortunately, we don’t have a way to support sockets right now. It may be something we develop in the future, but we don’t have a great option for you at the moment.
