Yes, for ePost that is correct:
[On a related note, following Andrew's suggestion, I have updated CVS
to use the new base URL in Bio/EUtils/ThinClient.py]

No, Bio.Entrez does not support the WebEnv / history interface. It
can request data in different format types though, although it will
only parse the XML output.

This is a strong reason - although we are still using Bio.EUtils in
Bio.GenBank (and probably in other places too).

I think Michiel meant getting a handle containing raw HTML isn't very
sensible, and this is what the Bio.Entrez.query() function does. If
it can only return HTML, then I agree, its not very useful and could

Unlike BLAST where you may have a local webserver, is there any reason
for to use a URL other than the NCBI's one?
