Hi,

Is it possible to uncompress gzipped data coming over a socket?

As far I remember a message by Brian Ripley (I could not find it, though),
it's not possible directly. You have to save as a file and read from disk;
see docs on "connection".

Have a look at gzcon, for decompressing data as they arrive. From the
help file:

     ?gzcon? provides a modified connection that wraps an existing
     connection, and decompresses reads or compresses writes through
     that connection.  Standard ?gzip? headers are assumed.

There is no indication in the gzcon help file that explicitly prohibits
socketConnections. Also, see memDecompress for in-memory decompression
of the entire object.
