New Comment:
Sorry for delay with report - was a bit busy (I have made work-around
via moveing all download/transform features to spawned program)
Removeing ob_* does not matter, only I can't send headers if spawned
process shows info - the Header function set after echo `filter`...
In end of this comment I added script, that simplified (HTML parser
removed)
If you run an lot of requests at one time (I have tested in local by
pressing F5 key for a while) - then in directory of scrpit will created
several *.TMP files, and not removed.
if comment out line
echo `echo trans.exe $lang $infile $outfile`;
then no this TMP files left.
As you see, I have changed external filter to just echo, so this not
filter problem. This looks like problem of external app spawning...

And provide an actually working script..(one that COULD actually work)

Simplify your script..drop the ob_* stuff totally and
don't use any external apps on the files.
Does it work then? (add the new script here too)

Description:
------------
I tried to download file with curl, parse it with external app, show
output and kill temp file. But:
1. if php as isapi module - when several requests at one time some
inputs are locked! Filemon says that it frees by some cmd.exe after all
runned sub-processes already finished. Very strange!
2. if php as fastcgi - it often crashes with error in php_curl (all
latest dlls in system32 upgraded; php4ts only in c:\php, php4isapi also
in c:\php and no in c:\windows\system)
3. if php as cgi - all OK, except of when user cancelled download the
script terminated, but shotdown_procedure not called, so temp files
left.
Reproduce code:
---------------
<?ob_start(); $url="http://some.site.com";;
$oinfile = tempnam ("./", "URLIN");
$infile = preg_replace("#.*[/\\\\](.*?)#","\$1",$oinfile);
$ooutfile = tempnam ("./", "URLOU");
$outfile = preg_replace("#.*[/\\\\](.*?)#","\$1",$ooutfile);
register_shutdown_function(create_function('',
"@unlink(\"$infile\"); @unlink(\"$outfile\");
@unlink(\"$oinfile\"); @unlink(\"$ooutfile\"); return 1;"));
$inf = fopen($infile, "w");
fwrite($inf, "<meta http-equiv=\"Content-Type\"
content=\"text/html\">\n");
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_FILE, $inf);
$st=curl_exec ($ch);
curl_close ($ch);
fclose($inf);
echo `filter.exe $lang $infile $outfile 2>&1`;
ob_end_flush();
?>
Expected result:
----------------
No .tmp files not in windows\temp\ folder, not in script folder.
Actual result:
--------------
Some .tmp files left and in windows\temp, and in script folder.
