HIT COUNTER AND CASHE-CONTROL

hi, I m facing two problems rite now , I can't force my page to revalidate by using the following code on my "index.php" page. header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1 header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); // HTTP/1.0 My Index.php page has a flash intro which reads a text file counter.txt and displays the "visitor counter" i use PHP script to increment the counter in the Text file and on the same page read it from flash. Problem 1 : when I again press the refresh button in Internet Explorer ( Instead of increasing counter in the text file it doesn't displays increment on flash ). is it about Cashe Control ??? if yes then why the above code i wrote is not doing its work ?? Problem 2 : When I Upload "index.php" to a hosting server then I get the PHP Error Message "PERMISSION DENIED" "CANT OPEN FILE with "w" Mode" "Invalid File Handle" etc. So I thought it is a permission Error, I will ( as a last attempt ) change the permission on the hosting server by consulting my hosting company but .......... Is there any other way to implement " HIT COUNTER " ?? and displaying Hit Counter in Flash Intro ?? Thanks a Lot for the help raheel --------------------------------- Do you Yahoo!? Yahoo!
