redirecting to a content page

[Shreyas]

I am a new user writing some scripts to store data entered via a
browser into a database. I have several content pages, and one
"processing" page. A content page often has a form like this:

<form method=POST action=processing.py>
<input type=text name=username>
....

And the processing page goes like this:

form = cgi.FieldStorage()
## do some work, put data into the db

The thing is, processing.py doesn't have any content that I want to
display to the user. I would ideally like processing.py to seamlessly
send the user back to the content page that it came from, perhaps with
some parameter tweaks.

Instead, I am having to write intermediate steps like this into
processing.py:

Return to the <a href=contentPage.py?submit=true>page</a> you came
from.

Please let me know if there's a way to do this, or if my general
approach (having such a processing page) is off.

Thanks,

Shreyas

sure what it is called...

And this is a GoodThing(tm). A successful post should always be followed
by a redirect.

import cgi

print "Location: %s\n\n" % url_of_the_page_you_want_to_redirect_to

Nope, having a separate script doing the form processing, then
redirecting is the right thing to do.

It's a redirection. If you are to work with CGI (or any other web
programming solution FWIW), you'd better know the HTTP protocol.

Really? Why's that?

Thanks much, Location: took care of what I needed. I'll look to the
http protocols for the future.
