lubcups also looks as a considerable alternative, and it contains a generic HTTP client. Though it will look a bit strange if scanner plugin will depend on a CUPS API library :-)
libcups is usually present, especially as nowadays most scanners (and especially most Linux-friendly ones) have this test page generation unit under the scanning mechanics :)
In my opinion libcups should get moved into a project separate from cupsd, as it is the standard implementation for IPP in free software, and with the PWG (Printer Working Group, http://www.pwg.org/) IPP Scan and IPP System Service libcups will not stay a print-only thingy but will also serve for scanning and other things.
