Your PCs cache is usually a good thing, but where DX objects using XML feeds are concerned it can be a pain.


The reason for this is that most users don't set their PC to check for a new page each time, but rather reload from the cache, especially if it's the same day.

Fortunately there is a solution!


The logical solution is that you ensure that the DX object checks for a new page every time. The best way to do this is to actually send the user to a different page every time.


What! How is that going to work?


Well, most XML feeds work on a parameter basis. What's cool about this is that if a page receives a parameter it doesn't recognise, it ignores it. Are you getting a hint here? Well yes, the solution is to append a dummy parameter to each request.


Let's take a weather object for example:


The normal request is this:

http.Open "GET", "http://xoap.weather.com/weather/local/" & Object.PersistStorage("zipcode") & "?cc=*&dayf=5" & str_RANDOM_URL, False


Now, lets amend that:

Randomize
str_RANDOM_URL="&rnd=" & rnd()
http.Open "GET", "http://xoap.weather.com/weather/local/" & Object.PersistStorage("zipcode") & "?cc=*&dayf=5" & str_RANDOM_URL, False


All of a sudden, the browser is being requested a brand new page due to the random number. The webpage returned is the same as what would normally be returned, but now you get it as and when the timer requests it.
