OS/2 Gopher Server
 
IBM has a rather clever Gopher server for OS/2. It is available as 
GOSERVE.ZIP in all the same places that the Gopher client is 
distributed. Each arriving Gopher query launches a REXX program, which 
examines the request and returns either the data or the name of a file 
to transfer. This provides a very flexible and powerful system for low 
volume activity. The overhead of starting a REXX program probably 
precludes its use as a Enterprisewide Information System.
