Also, if the files are not readily available, the user can't download them, but the server obtains a copy of the requested file and notifies the user by mail when he can get the file. We expect files to be tipically from 2 to 50 gigabytes in size, for now. I just want to check if it's possible to write a Web

PHP - determine how many bytes sent over http

阅读更多关于 PHP - determine how many bytes sent over http

问题 Is it possible in PHP to get a count of the number of bytes transmitted to the client? For example, if I'm outputting a 10 MB file, is there a way to find out if all 10 MB were sent to the client, or to see if the client interrupted the transfer partway? I know Apache will log this afterwards, but I'd like to access the data in PHP. 回答1: Take a look at the ignore_user_abort and connection_abort function. 回答2: Here's what I ended up doing (thanks Gumbo): ignore_user_abort(true); $handle =

Atomic file copy under .NET

阅读更多关于 Atomic file copy under .NET

问题 I am building a server app that copies files using System.IO.File.Copy(...) function. My files can be rather large, therefore, it has a fair chance that if the machine crashes, it happens during copying. After restarting the service, I should be able to pick up the copy tasks and continue. How can I detect if a copy has been successfully completed or interrupted by server crash? My current plan is to copy the files to a temporary name and once copying completed rename it to the final name.

Comparing HTTP and FTP for transferring files

阅读更多关于 Comparing HTTP and FTP for transferring files

What are the advantages (or limitations) of one over the other for transferring files over the Internet? (I am aware of secure forms of both protocols. I'd like to hear comparisons through personal experiences in terms of performance, reliability, file size limitations etc.) John Ellinwood Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There
