Traffic Server plugin for header based reverse proxying
Hi All
Am trying to setup Apache Traffic Server as a reverse proxy. I was
successfully able to set it up.
But now my issue is how to forward the request based on the header
content of my request.
I went through the remap and header plugins but not able to relate it to
my needs.
Is there any way to create a plugin which will satisfy my need ?
Could anyone help me on this.
Regards
Achuth

There's no formal documentation, but you can see some examples here:
https://github.com/apache/trafficserver/tree/master/plugins/experimental/lua/examples
These examples cover all the functionality that is currently supported. For your use case, we would need to add support for transformations, which we don't currently have. I'm slowly working on improving the Lua plugin, but I'd be very happy to help if you were interested in enhancing it.

Thanks Leif, can you point me to some lua plugin documentation as
unfortunately I am only getting C++ doc.
Also I would like to know if I can read the body of the http request too
using Lua to search for keywords.

Yeah, you have two choices:
1) Write a plugin in C/C++. You have access to all request headers
easily.
2) Write a Lua script using the Lua plugin.

Yeah, you have two choices:
1) Write a plugin in C/C++. You have access to all request headers easily.
2) Write a Lua script using the Lua plugin.
