Topic: mod_substitute (or similar) with external substitutions

[AfraidOfFeathers]

Hi all,

My aim is to substitute fields in a document body using an incremental counter and storing the substitution. In other words I seek to redact certain fields.

If the input body contains is "hello", "hello", "hello" then the proxy server should capture each substitution and replace it with an identifier.

The output could be "1", "2", "3", and the substituted text would be stored elsewhere such as 1:hello, 2:hello, 3:hello.

Then.. I want another proxy that does the same but in reverse. The second proxy should substitute the identifiers with the text that is stored elsewhere.

Alternatively the proxies could replace values with encrypted values, removing the external data storage.

Which Apache mod can help me to do this?

Thanks!
