Review Comment:
   I am actually thinking of using foreign function instead for this. e.g. in 
envoy it has "compress and "uncompress" foreign function exposed to wasm 
modules.
   
   This is how it is defined - 
   
https://github.com/envoyproxy/envoy/blob/d12d47b05a832ce04d9130a869fa72f7ddbcef28/source/extensions/common/wasm/foreign.cc#L43
   
   This is how it is used -

   Please take a look and see if we can implement this using foreign function

Review Comment:
   It should be ":scheme" instead according to

   Please check out the section in pseudo-headers.
