I have a web service that is going to need to transfer back to the calling
program a file. The file can be up to 1MB in size. What's the easiest way to
do this?
I could do an HTTP get on the file but being as how that's not secure it
doesn't leave me feeling very comfortable.
Any thoughts/suggestions?
TIA - Jeff.

Hi Jeff,
You can read the file into a byte array and return it from the web-service.
The major disadvantage is that the binary data will suffer a base64
transformation, therefore increasing the overall size. Despite of this
disadvantage, this is IMO the best choice at this time: you could use DIME
or MTOM (both allow you to transfer data in its raw mode), however DIME is
part of WSE toolkit and do not really compose very well with the remaining
WS-* specs - also, is mainly supported by Microsoft; Concerning MTOM: this
will be probably the best solution, however it is not available at this
time... I think we'll have to wait for WCF (aka Indigo).

I agree about MTOM being the best solution to your problem, but you don't
have to wait for Indigo (by the way, the official name is "Windows
Communication Foundation", quite somptuous, ain't it ;-)). You can use Web
Services Enhancements 3.0. The current available version is still CTP right
now, but the RTM version it's going to be available soon (sooner than Indigo
anyway).

Yes, you're correct. I forgot WSE 3.0.

I was downloading from the MSDN subscription site and
used the File Transfer Manager, and was wondering if that
was something I could use for my site? Is there an API
that allows me to build this functionality into my
website? My problem is that I have a site that has
hundreds of files on it, and my customers would like to
select 5 or 6 of them and queue them up to download.
Is this possible?

Hi;
I created a virtual directory in IIS 6.0 and my asp.net app runs fine. But
when it tries to write a file I get:
Access to the path is denied. - C:\Inetpub\wwwroot\RunReportASP\images
C:\Inetpub\wwwroot\RunReportASP is the directory of my virtual directory for
