Upload/Download Files Via WS

[Demetri]

Hello,

I'm involved in developing an application which has the need to transfer
files automtically once a laptop is connected back to the network. The
application i'm developing will automatically realize the network is
available and thus pass a file to a web service that will know what to do
with the file.

My question is what is the best way to transfer a file via a web service
that my application will consume to invoke transfer's either way (upload or
download)?

And what sort of security is best? Security is a concern - would not want
sneaky people intercepting the information.

Thanks for any opinions or input on approaching a solution to this.

You can go ahead and use the WS2.0 , DIME attachments to transfer files, You
can go ahead and compress files using GZIP before uploading them and
decompressing them when you download, if you want to preserve some
bandwidth.

WS-Attachments (nee DIME) work very well in this scenario -better than
simple byte arrays on web methods. You can get DIME support if you install
the WSE2 SDK. Just remember to keep your upload sizes below 4MB at a time.
The whole thing breaks down once you go past 3.8MB or so.

want to create a webservice which will be used for uploading the file to the
server hosting the Web service.
I have seen some sample but of no use.
Note :

1. I want to upload file upto 50 MB ? This is possible with DIME/WSE. but
this will be achieved
using Chunking ? how can I achieve Chunking in my application is it inbuilt
feature or I have to write the complete code for this ?
2. I am using WSE 1.0 with .net 1.1
what is the best approach to achieve this ?
If any body have implemented ? plz do send some sample code .
Thanks in advance
