Details

It is a simple http client. So it does not take care of special chars e.g. whitspaces. For details see e.g. perl HTTP::Request::Common documentation and http://www.w3.org/Protocols/rfc1341/0_TableOfContents.html

Run this code

# NOT RUN {
#to test uncomment. First check that the host is running.
#port <- 80
#test2 <- list(
#	"fruit"="apple",
#	"dat_defs"="20021204/F113213.dat",
#	"myimage"=list(
#			"filename"="myimage.raw",
#			"object"=as.raw(as.vector(mymatrix))
#		),
#	"upsa"="test"
#)
#postToHost("www.molgen.mpg.de", "/~wolski/test.php4", test2,
