Lacking, needs updating.

While its nice to use for small tasks, the POST body text area should be a sheet as its not large enough for working with XML or large bodies. The app also really needs to be updated to support versions.

Other minor improvements would be great since its commerical now, such as cookie storage and management on a per document basis.

Update: Two years later and I’ve finally given up on this developer updating his stuff. The other day I had data trailing my xmls closing tag, making it invalid XML. For some reason HTTPClient did not display that… causing me to think my API was okay and sending me down a different path troubleshooting. DONE. $rm -rf /Applications/HTTP Client.app
