Resuming downloads ?

[Marcus Crafter <cr...@managesoft.com>]

Hi All,

Hope all is going well.

I've searched the archives for an answer to this question, but so far no
luck - it's definitely a simple one! :)

Has anyone written any code around HttpClient to allow resuming of
downloads that have been interrupted due to some reason ?

I'd like to be able to use HttpClient in our application but require this
functionality and aren't sure if this is implemented inside HttpClient (as
part of some spec?) or if it should be implemented outside of HttpClient
at the application level using partial retrievals, etc.

Any ideas, code, suggestions, etc, greatly appreciated.

Cheers,

Marcus

There is not any explicit functionality in HttpClient for handling 
resumes but it should work.  I believe download resuming is just part of 
the standard 1.1 spec.  You should only have to add a few headers to the 
GetMethod before executing it.  Take a look at:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.3
and
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35
