URL fails with IdHttp.get, works fine in browser

The following URL works fine when pasted into a Browser:
http://tigerweb.geo.census.gov/ArcGIS/services/tigerWMS/MapServer/WMSServer?&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&LAYERS=Linear%20Hydrography&STYLES=&SRS=EPSG:4326&BBox=-91.64,43.30,-91.36,43.53&WIDTH=542&HEIGHT=671&FORMAT=image/jpeg

But you get "invalid request" from the server when you use this URL in idhttp.get(URL,stream);

Any ideas - I think it may be something in the http header that indy is sending?

Try to set Request->UserAgent to Mozilla/3.0 for your idHttp component

Thanks, that's apparently the default, and that's what I've been using - sadly, it doesn't work. Is there another option for the UserAgent?

Added background:
I've left everything in the IdHttp at default settings.
the Actual response I get is "HTTP/1.1 400 Bad Request"

Marco Gasi

From Delphi 7 up to Delphi 2010 the default value for that property is "Mozilla/3.0 (compatible; Indy Library)" and this raises a bad request error: setting the value to simply "Mozilla/3.0" solved my problems. Be sure nothing is after "Mozilla/3.0".

If this doesn't helòp you, unfortunately I can't figure out any other solution...

The WinINET approach with Delphi is well documented and there are plenty of examples posted on line that actually work - no more time right now to mess around with Indy's HTTP component.
