x-sendfile

I am in a situation, when I have to implement downloading of large files(up to 4GB) from a Web server: Apache 2.4.4 via HTTP protocol. I have tried several approaches, but the best solution looks to be the usage of X-SendFile module. As I offer progress bar for file uploads, I would need to have the same feature for file downloads. So here are my questions: Is there any way, including workaround, to achieve file downloads progress monitoring? Is there any way, including workaround, to calculate file download transfer speed? Is there better way to provide efficient file downloads from a web

I am trying to configure Rails production server with Apache 2.2, Passenger 4.0.59 and XSendFile 0.12. Application is deployed via Capistrano. Deployed application produces (maybe large) PDF to #{Rails.root}/tmp and serves this file using send_file . The problem is that Capistrano uses symlinks to point to currently deployed version of application. XSendFile on the other hand dereferences symlinks and refuses to serve a file if its real location is outside document root even if it is allowed by XSendFilePath . Apache's error.log states: (20023)The given path was above the root path: xsendfile:

I'm trying to make X-Sendfile work for serving my heavy attachments with capistrano. I found that X-Sendfile is not working with symlinks. How could I handle the files inside a folder symlinked by Capistrano so? my web server is apache2 + passenger in my production.rb : config.action_dispatch.x_sendfile_header = "X-Sendfile" in my controller action : filename = File.join([Rails.root, "private/videos", @lesson.link_video1 + ".mp4"]) response.headers["X-Sendfile"]= filename send_file filename, :disposition => :inline, :stream => true, :x_sendfile => true render nothing: true my filesystem

Some time ago I wrote a question regarding the use of temporary files within a rails app. On thar particular case, I decided to use tempfile This causes a problem if I also want to use the x-sendfile directive ( as a parameter in Rails 2, or as a configuration option in Rails 3 ) so that the file sending is handled by my web server directly, not my rails app. So I thought about doing something like this: require 'tempfile' def foo() # creates a temporary file in tmp/ Tempfile.open('prefix', "#{Rails.root}/tmp") do |f| f.print('a temp message') f.flush send_file(f.path, :x_sendfile => true) #

I'm trying to install the mod_xsendfile Apache Module on Windows (7) x64 (using Apache 2.2) -- yes I'm doomed from the get-go, I know :-). Apparently there is : a) No Win x64 binary for mod_xsendfile, just a Win32 binary from the module's website b) No Win x64 binary for apxs from ApacheLounge I've tried the usual LoadModule xsendfile_module modules/mod_xsendfile.so but the semi-obvious error ( httpd: Syntax error on line 127 of C:/Apache/conf/httpd.conf: Cannot load C:/Apache/modules/mod_xsendfile.so into server: The specified module could not be found. ) occurs, it's not Win x64 compatible.

I'm running into an issue using xsendfile with my Rails 3 app. I'm using capistrano to manage deployments and in each release, there is a symbolic link to the shared/assets dir (e.g. /var/www/site/releases/1234/assets => /var/www/site/shared/assets). The problem is that that XSendFile doesn't seem to follow the symbolic links. In my apache logs, I'm seeing the following error: The given path was above the root path: xsendfile: unable to find file: /var/www/site/releases/20110406205607/assets/pdfs/2/original/test.pdf I have the XSendFilePath config set as XSendFilePath /var/www/site/shared
