• How does IIS persist a user's identity from page to page?

  - by Rising Star

  Web pages are, by nature, state-less objects. When you click from page to page in an ASP.net application, each request for a page is treated as a brand-new request. We use things like cookies, session-variables, and query strings to maintain state from page to page. When you log in to an ASP.net web application using Windows Authentication, how does IIS persist your identity between pages?

• Replace always replacing null values

  - by Mike

  Why does left(FIELD, replace(nullif(charindex('-', FIELD), 0), null, len(FIELD))) always return null? The idea behind the query is that if charindex() returns 0, then convert the results into null, then convert the null into the length of the field. So if '-' does not exist, show the whole string. For some reason it makes every row equal null. Thank you.

  - by Shaul

  My database has about 30 views, most of which have a reference to another database on this server (call it DB1). Now, without going into the reasons why, I need to update all those views to DB2, also on the local server. I would hate to have to do this manually on each view. Is there some SQL query I can run that will replace all occurrences of the string 'DB1' with 'DB2' in all my views?

• How to get final destination URL from AJAX?

(http://stackoverflow.com/ in the example) I checked in the response headers but I cannot seem to find it. (I just used the GET/POST method not HEAD).
