clearing cache

[andyd34]

I am having an issue with ie7 and cant seem to get my head round it as the issue is not present in firefox

 

I am submitting a form and then redirecting back to the form page but the original values are still showing in ie7 until I refresh the page. I have tried adding

header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); 

 

but it hasn't made any difference. This form is loaded via jquery and its in a phpbb3 template file. Can someone please help

Are you sure that you are not storing the values somewhere like sessions for example to handle error situations and re-display the values in case of error and then displaying these stored values in the form printing page? The form values should not be present anymore after redirect. I don't think cache is the issue here (I might be wrong also). Maybe show more of your code?

Positive, its just a standard form, its submitting fine and all is well in ie6 and ff3 on windows and ff on ubuntu its just ie7 thats why i cannot figure it out. Anyway here is the code

 

ucp_profile_profile_images.html

<!-- INCLUDE ucp_header.html -->
<script>
$(document).ready(function(){
	$("#load_images").load("./ajax/load_images.php");
});
</script>

<div id="upload" ><span>Upload File<span></div>
<h3 align="center" id="status" ></h3>
<ul id="files" >
</ul>
<br clear="all" />
<div id="load_images"></div>


<!-- INCLUDE ucp_footer.html -->

 

./ajax/load_images.php

If i open ./ajax/load_images.php in ie7 then press f5 and go back to the form page its refreshed until i update it again

Now that I think of it, if it works in all other browsers it should not be a code problem. And the database gets updated as it should when you press submit? Sorry but I don't really know what would be wrong now, all looks ok. Have you tried adding the HTML meta no cache tag to the ucp_profile_profile_images.html?
