title: Do I need to use http redirect code 302 or 307?
body: <p>Suppose I have a page on my website to show media releases for the current month
  <br /><code>http://www.mysite.com/mediareleases.aspx</code></p>
  
  <p>And for reasons which it's mundane to go into*, this page MUST be given a query string with the current day of the month in order to produce this list:
  <br /><code>http://www.mysite.com/mediareleases.aspx?prevDays=18</code></p>
  
  <p>As such I need to redirect clients requesting <code>http://www.mysite.com/mediareleases.aspx</code> to <code>http://www.mysite.com/mediareleases.aspx?prevDays=whateverDayOfTheMonthItIs</code></p>
  
  <p>My question is, if I want google to index the page without the query parameter, should I use status code 302 or 307 to perform the redirect? </p>
  
  <p>Both indicate that the page has "temporarily" moved - which is what I want because the page "moves" every day if you get my meaning.</p>
  
  <p>[*] I'm using a feature of a closed-source .NET CMS so my hands are tied.</p>
