download timeout

[DrByte]

Using Download By Redirect is the same as using http like you mentioned before. All it does is create a download point, and points the customer to that to do the download the same as if they'd clicked a link you supplied in an email.

apparently not, as the alternate (outside/separate from zen cart) links i provide to customers works every time.

just to be sure i wasn't crazy, i switched redirect to TRUE, made sure /pub was 777, throttled my bandwidth to 50k/s (to be sure it'd take a long time to download), and as predicted, the download ended prematurely after only 57MB.

this is a serious problem

After much struggles in getting my client's downloads to complete successfully - (some zip files are over 50MB and many were timing out before completion), I finally worked out the issue with the help of this thread.

My Hosting company (which i cannot say enough good things about) worked diligently with us to sort out any issues that may have been on their end. However, after much testing with the Firefox "Throttler" add-on (to slow downloads and simulate a dial-up customer's experience) we were still experiencing problems with incomplete downloads ending abruptly at around 20 minutes!

This thread finally held the answer. Despite no mention of this limitation in the Zen Cart "Download delivery methods explained" tutorial, the fact is that Zen Cart comes hard coded for a max time of 20 mins. Upping this was our answer!

Please, Please, add a reference to this fact in the Tutorial: https://www.zen-cart.com/tutorials/i...hp?article=292
so that others can be saved untold time and frustration.

Maybe a future ZC version should have this value somewhere within the Admin so it's more easily discovered? Just a thought...

Otherwise, thanks for a great product and instruction.

I'm having a very similar problem with a customer using dial-up to download a 5 MB file - it times out at about 20 minutes.

Where is this 20 minute limit set, and how do I change it?

I suspect tht it is a php parameter and not a ZenCart setting

OK, I just did some searching of the entire Zen Cart installed code using CEDIT, and came across something that looks like it may be where it happens:

Starting at line 143 in includes/modules/pages/download/header_php.php

if (DOWNLOAD_BY_REDIRECT != 'true' or $link_create_status==false ) {
  // not downloading by redirect; instead, we stream it to the browser.
  // This happens if the symlink couldn't happen, or if set as default in Admin
  header("Content-Length: " . (string)$zv_filesize);
  if (DOWNLOAD_IN_CHUNKS != 'true') {
    // This will work on all systems, but will need considerable resources
    $zco_notifier->notify('NOTIFY_DOWNLOAD_WITHOUT_REDIRECT___COMPLETED');
    readfile(DIR_FS_DOWNLOAD . $origin_filename);
  } else {
    // override PHP timeout to 20 minutes, if allowed
    //@set_time_limit(1200);
    @set_time_limit(4800);	// test at 1 hr, 20 min for dialup.

Note the last 2 lines, where I set the limit to 4800.

I set an email to him to test this, should know by tomorrow if this works.

If it does, I'll want to copy this to the appropriate folder in modules/orcatools/pages/ to be sure it'll override any updates.

I'll let you know how it goes.

There is no "classic" folder under /pages - - so these are not overrideable

Nice find but note "if allowed"
