Right now in our WSE 2 we're using DIME. DIME is fine for downloads, uploads
on the other hand are a pain in the a.s because of the DIME limit and IIS
limits.

Now I'm switching to WSE 3 + MTOM and I've read all over the place that it's
reliable for very large files. Great, but what about HTTP based web services
on IIS? Am I going to have to change anything on the IIS server to make it
do more than 4 meg files??

Should I stick with chunking? (yukky mess)

Thanks,
James Hancock

Yep, you'll have to add the following to your configfile:

<configuration>
<system.web>
<httpRuntime maxMessageLength="409600"/>
</system.web>
</configuration>

ms-help://MS.WSE30.1033/WSE3.0/html/4344d43e-ceb4-43a9-8f8c-6a3f89f786bd.htm

However, if I was you, I stick with chuncking, or rather MTOM and chuncking,
since it only seems to be possible to stream data from server to client, and
not the other way around.

Søren

It would be fine if all I had to do was update my web.config. What I'm
concerned about is that IIS is going to do what it did with DIME and kill it
with > 4meg uploads regardless of what you set in your web.config unless you
go and edit the machine.config file, which isn't acceptable.

Have you tested uploads with IIS > 4 megs? Has anyone?
