You can tell the library to not use PQA compression with:
DWord dw = ctpConvNone;
INetLibSettingSet(LibRef, IHandle, inetSettingConvAlgorithm, &dw,
sizeof(dw));
LibRef and Ihandle you would get when you find and initialize the
library.
However, this will run up the user's transmission costs and run down
their batteries. If you are sending a lot of data, I'd use your own
compression (compress at your server, decompress in your Palm app)
because the PQA compression isn't particular effective. If you are just
sending simple web pages, I'd use PQA style compression. It is pretty
simple. Basically, HTML 'tags' are converted from text into 2 byte
'commands'. Also, lower case characters are encoded into 5 bits. There
is a 'command' to turn encoding off, so long strings of upper case
letters (which can be two byte 'escaped') don't expand in size.
The format is documented in the PALM QUERY APPLICATION FORMAT
SPECIFICATION, which can be found at the Palm web site.

Not quite. For PQAs it decompresses it. Using the INetLibrary,
unless you tell it to feed you uncompressed data (which I don't know
how to do), it will apply the same kind of compression it does to PQA
pages.
