it should work since you request an URL that's not cached from previous loads.

Did you reuse the job or did you DIM a new one every time. The last said should be the one you are doing...

it might drop the parameter since it's posting tho.

last thing you could try is add an header in the php file so that the page expires immediatly.

B4X:

header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

Hi Manfred, After declare job object then I use the poststring method, get content and release at final. For next req, I do the same thing, then job is new created every time. I notice that the second req is too fast seem no fetch and so no new data loaded. And I just doubt that why it work on simulator but not work on real device (via b4a bridge).

Click to expand...

What do you mean with the same thing? Does your "same thing" include the DIM???

B4X:

Dim Job As HttpJob

Maybe you should upload your project (export as zip) and we can have a look at it

If you have control over the php-file then you could insert logging-functions into it so see all given parameters

PHP:

$file_handle = fopen('./b4a.log', 'a+');
fwrite($file_handle, "======================================"."\r\n");
foreach($_REQUEST as $name => $value){
    fwrite($file_handle, date("d.m.Y H:i:s", time()).": ".$name."=".$value." "."\r\n");
}
fwrite($file_handle, "======================================"."\r\n");
fclose($file_handle);

chaiwatt: since the parameters are all small you could go for get instead of post with the randomize in the url as parameter.
(don't forget to search/replace the $_POST with $_GET in the php file)

I dont know whether it helps but you can try

B4X:

Dim o As Reflector
o.Target = WebView1
o.RunMethod2("clearCache","False","java.lang.boolean")

this code cleares cache fro webview. Dunno if it also clears http-job temporary data

true, I requested the randomizer trick into the fetch routines before but I'm not sure if Erel will add it.
