php - Any documentation about how Apache handles file uploads? -

I have spent hours walking, as well as searching for Apache site, and I can not find any documents about this. How Apache file upload handles ??? Especially the older ones have read that until the upload is completed PHP is not included, which I expected. But as far as Apache uploads, I can not find anything.

The reason for this is that I am hot for the document because Apache uploads completely in memory, instead of streaming them to the disk, httpd Byte, unless I'm not using it until it crashes. Generally the amount of physical memory consumed is 3x file upload size, and increases to around 5 MB / s (anywhere near the speed of my uploads).

I have requested this request on any other LAMP stack, and Apache memory usage is not fully changed during upload.

Can anyone tell me how Apache can handle the same uploads differently on two different servers? Any idea greatly appreciates.

  Technically, PHP  is  handling Apache's upload, And buffer the file in RAM until it is complete, however, your script will not be able to get control until the upload is completed (or shut down). Apache will not automatically buffer the disc until it is not. Think of it as an invisible "handle_upload ()" function call that is inserted transparently as the first thing in your script.  
 "Everything is a CG script", not embedded in the webserver process, the post data was sent to the CGI script via standard input, the file converts the CPI process directly into Apache and reads byte-by-byte Can go because it came in.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
