Clearly. You should, though. Otherwise you're going to hit all the pitfalls we've been telling you about repeatedly, and all you'll be doing by doing it in AJAX instead is building your own slower, buggier, flock-over-http protocol from the ground up.

Issue is server doesn't release the file to be read.
Doesn't release the file? What error do you get when you try to retrieve it -- does it think the file's not present at all, or give 'permission denied', etc. Either is quite odd, most UNIX systems don't do mandatory locking of open files, nor play tricks to hide files until they're complete; what system are you using?

ECACCESS-FILE-GET(1p)					User Contributed Perl Documentation				     ECACCESS-FILE-GET(1p)

NAME

       ecaccess-file-get - Download an ECaccess File

SYNOPSIS

       ecaccess-file-get -version|-help|-manual

       ecaccess-file-get [-debug] [-progress] [-offset number] [-bufsize length] source-ecaccess-file [target-local-file]

DESCRIPTION

       Allow downloading the source-ecaccess-file. If no target-local-file is specified then the source-ecaccess-file name is used.

       The source-ecaccess-file is in the form [domain:][/user-id/]path. Please read the "Shell commands -> File Management" section of the
       "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-ecaccess-file
	       The name of the Source ECaccess File.

       target-local-file (optional)
	       The name of the Target Local File.

OPTIONS

       -progress
	       Provide a progress meter on the standard terminal, allowing to monitor the file transmission in real-time. The progress bar is
	       removed from the terminal when the transmission is done. This option is not supported and ignored on Windows platforms.

       -offset number
	       Every open file has an associated file offset, which determines where the next read operation will start. This number is set to 0
	       by default.

       -bufsize length
	       Specify the length of the buffer (in bytes) which is used to download the file.	The larger the buffer the smaller the number of
	       http/s requests. By default a buffer of 1048576 bytes(1MB) is used.

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-get -progress bin/a.out

       Download the a.out File in the $HOME/bin directory of the authenticated user. The Target File Name is a.out. A progress bar is displayed
       during the transmission.
