[R] see rcurl contents before they're sent?

[Mark Miller]

I am trying to use the R / solr integration from
https://github.com/datadolphyn/R/blob/master/r_solr_integration.R

I have the query function working, but I'm having trouble with the post
functions, which uses rcurl.

Is it possible to see the string that rcurl is going to send to a webserver
(instead of, or in addition to send it to the server?)

thanks,
Mark
