Supplying Login Details to a Web Site

I want to automate a process I do daily which involves logging into a web site, screen scraping a specific page, then formatting and exporting the data to Excel.

I have found examples for most of what I want to achieve with Mathematica, but am uncertain how I can post back my user name and password to the web site in question.

Any suggestions or examples?

Thanks in advance

How to do this depends on the website and how they implement their username and password login.

In many cases you can use URLFetch, which is a lot like wget in linux.

For an example of how this, see:

There are likely other examples of URLFetch being used. I would also look up examples with wget which will have many more examples online.
