There is no bug in ns_returnfile. It is possible that you can modify your program (something like): set tempfile myfile.txt set tfd [open $tempfile w+] file delete $tempfile exec /some/external/program >@ $tfd set tlen [tell $tfd] seek $tfd 0 ns_returnfp 200 text/plain $tfd $flen close $tfd Tclsh Example: [EMAIL PROTECTED]:~/Software/tcl/fd$ tclsh % set filename hi.txt hi.txt % set tfd [open $filename w+] file5 % ls hi.txt % file delete $filename % ls % exec echo "hi there" >@ $tfd % tell $tfd 9 % seek $tfd 0 % gets $tfd hi there % gets $tfd % tell $tfd 9 % seek $tfd wrong # args: should be "seek channelId offset ?origin?" % seek $tfd 0 % gets $tfd hi there % ls % close $tfd % exit Working AOLserver example: set directory [file dirname [info script]] set filename [file join $directory tmp.txt] set tfd [open $filename w+] file delete $filename exec echo "hi there" >@ $tfd set flen [tell $tfd] seek $tfd 0 ns_returnfp 200 text/plain $tfd $flen close $tfd ## Trying this via telnet: [EMAIL PROTECTED]:~/Software/tcl/fd$ telnet rmadilo.com 80 Trying 126.96.36.199...
