While trying to access a website, a js file is not getting downloaded properly. Size of this js file is 1.5MB and only 200b are getting downloaded. Tried downloading the specific file and i got a progress indicator and downloaded successfully. Disabled the progress indicator and tried the website and it worked. So what is the link here?
It depends on specific app behavior. Most of the apps are ok, but some do not expect delays in downloaded data. The proxy needs time to download whole data and do malware scan before send them forward to app. To solve this, proxy use trickling ie sends small part from beginnng of the downloaded file until malware scan finish. We saw several apps, which gets few first kb and brakes the connection because they got tens of kb instead of expected bigger data.
