I have a client/server application which uses webservices functions to upload
large byte arrays to the server and httpwebrequests to download the data
files.  I would like to use http to also upload but am lost in how to
implement this.

basic information:
My Url looks like this  
"http://144.115.108.xxx/webservice1/myvirtual/videofiles/"

I want to be able to upload a large binary file to my server called
filename.gz and place it in the videofiles folder on my server.  

Up to this point, I have used webservice functions to upload data to my
server. Now I am faced with moving very large files ~300mbytes.  I am
assuming http is the best way to do such heavy lifting.  Can I see a simple
example of how to use httpwebrequest or fiewebrequest to move move a file to
a virtual location?

Thanks,
Fred
