Batch Updates From External Sources in C#

Okay, let's try this again. :)

I have database, with a table with 3 fields. ID, URL, BODY.

I then have a spider, which is running and handing me url/body pairs.

From there, I have a cache of the db table. Using this cache, I can tell if a url is in my db or not. For urls that already exist I have to update them. So...

I am creating a DataTable, an creating a SqlDataAdapter. From there, using the cache, i create a DataTable of all the exising urls. From there I want to BATCH UPDATE all of them at once.

I need a sample that does this using the DataTable and SqlDataAdapter. OR I need an alternative method for BATCH updating all of the URLS. I actually really love SqlBulkCopy, but it apparently does not update.

Things you should not offer me as a solution. If you do I will kill a kitten:

1) Tell me to use an Insert Command

2) Tell me to update the urls one at a time.

3) Tell me to use a dataset. I can't use [url removed, login to view] because I don't have or want to have the data in mem. The cache is a special creation for optimization.
