IE not working like firefox does

[Justin Fox]

Ok, I have two ajax functions on a webpage, one that gets data
from a php page based on the selection of a date from a datepicker.

Then another function that sends data to a php page on completion
and submition of a form.

in IE if I select a date, fill out the form the data gets inserted into
the database via php fine, and then it redirects to a payment page.
But if I hit the back button, and then choose that same date again, the
data that my "getter" ajax function returns isn't updated. Now if I close
the browser, open a new one, go to the page and choose that date then the data return is the updated/current data for that date.

In FF this is not the case, it works just fine (like it should) and calls my ajax function and sends/gets data just fine.

whats going on with my IE???

Thanks,

Your request is cached like all GET requests should be.

If you are rolling your own XmlHttpRequest code, you can add

xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");

or set the headers on the request itself.

code:
--------------------------------------------------------------------------------

xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT");

--------------------------------------------------------------------------------



or set the headers on the request itself.

where would I put this code at? after my onreadystate == 4?
Or what?

and for that date string, would I just use a "new Date();" and get the
string value?

You would put it with the open, send area of your code and you do not have to change the date

Cool man,

I really appreciate your help. I never realized that the actual
requests could get cached, I thought only pages get cached in the browser.

I'm going to try that tonight to see if it works, if I run into
any problems I'll just post again .

Requests don't get cached. It's their responses that get cached, and a page is just one type of response.
