Hi,
My upload script which uses upload hook works really nice. After the
upload ends it writes some debug stuff to log file and sends some info
to other host.
When client aborts the upload the reminder of the script after hook is
not executed and i get an error in my apache log:
[Sat Mar 26 14:53:09 2011] [error] [client xxx.xxx.xxx.xxx] (70014)End
+ of file found: Error reading request entity data, referer: http://lo
+calhost/upload
[download]
I'm thinking its the fault of apache, because without abort the script
works just fine. Does anyone have any clue about it ? The script:
#!/usr/bin/perl -w

Thank for replies,
