CGI: redirect some value to the previous URL

[Wenjie]

Hello,


I add an upload file feature to a BBS using perl. The
difficult thing is how I manage to integrate the upload
and message posting: the BBS is written using CGI.pm but
the posting code block is mainly HTML and javascripts
with perl variables, so my standalone upload.pl won't
work. Now I provided the URL of upload.pl for the user
to use the uploading function. But the user have to
copy and paste the uploaded file name and 'back' to
previous page. My question is: could I use some trick
to redirect the upload.pl result to the previous page
automatically?


Thanks and best regards,
Wenjie

It's the same technique that any normal CGI uses to re-direct really. It's irrelevant that
upload.pl is receiving file contents and saving it into a file vs. normally receiving key=value
pairs and parsing them in memory.

You can output an HTTP "Location:" re-direct tag, or output text/html containing meta-refresh or
javascript re-direct code.
