do i understand correctly, the problem happens with POST requests with large textarea content, but not with uploaded files. My suspicion is that it has to do with the content-type, that the browser switches between *www-form-urlencoded" and "multipart/form-data". can you check the content-type?

With which version of naviserver and which browser are you testing?

Never mind about the detail info: i was able to reproduce the issue. The problem was - as suspected - the handling of www-form-urlencoded with spooled content. This is now fixed in the updated version of NaviServer.

Gustaf, Thanks for that fix. We added the form.tcl to our naviserver . Should that work? We are getting an error message of

wrong # args: should be "try code ?catch? ?handler? ?finally? ?cleanup?"
while executing
"try {
set content [read $fp]
#ns_log warning "===== ns_parseformfile reads $file $form $contentType -> [string length $content..."
(procedure "ns_parseformfile" line 17)

We added the form.tcl so we did not have to recompile naviserver. I didn't notice any changes to other files for this fix.

what version of "try" are you using? "try" is builtin in tcl 8.6 [1] and there is an emulation in tcllib for 8.5. None of these versions provide the error message above.
