There was an excellent such primer on devshed, by Icarus, but they appear to have taken it down. I saved a copy of it to my HD.

But that looks to me like a javascript method. At a guess, it probably re directs the browser to some web script which checks the password. If so, knowing the address of that script, and the names of the keys it's expecting would be useful to you. They might be in the section of the page. If not, they might be contained in a *.js file somewhere. I have no idea whether this helpful at all. Just consider it speculation. -- www.wintergreen.in -- http://mail.python.org/mailman/listinfo/python-list
Question about smtplib, and mail servers in general.
Hi. I've been thinking about using smtplib to run a mailing list from my
website.
s = smtplib.SMTP("server")
s.sendmail(fromaddress, toaddresess, msg)
I know that in this instance, the toaddresses variable can be a variable
of type list.
Suppose the list contains well over 100 emails. Would that create some
sort of drain on the mail server? Would I be better off doing it in some
other way?

I did search google, and found a number of python scripts that already do the job (more or less). But when I try to tweak them to my specifications, I get errors ... probably because I don't really understand how the process of uploading a file via a webform to a cgi works. For e.g, take the script at this url. http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/273844 By reading through this script, I know that simply putting '' in your web form will establish a connection to the cgi when the client submits the form. The python interpreter obviously sustains that connection while the file is being transferred, the file being part of the FieldStorage() instance. But then, the script saves the file to the disk in some special way I don't understand. In this case: >fout = file (os.path.join(upload_dir, fileitem.filename), 'wb') while >1: >chunk = fileitem.file.read(10) >if not chunk: break >fout.write (chunk) >fout.close() chunk = fileitem.file.read(10), and fout.write (chunk) seem to be the key statements. Could someone elaborate on these for me please? And why do they need to be in a while loop? -- http://mail.python.org/mailman/listinfo/python-list
Uploading images via cgi?
How do I go about writing a cgi script, that will enable the client to upload things to a directory on my website? I would also like to write a script that enables the client to delete items in that directory if they want. Given that it's unix server, how do I go about ensuring the files are written to that dir with the right permissions? -- http://mail.python.org/mailman/listinfo/python-list
python image thumbnail generator?
Hi. I run a website for my band, and the other guys want an image gallery. I'm thinking it would be nice and easy, if we could just upload a jpg into a dir called "gallery/". When the client clicks the "gallery" link, a cgi script could search the gallery/ dir, and create thumbnails of any jpeg images that don't already have a thumbnail associated with them. The script could then generate a page of clickable thumbnails. A few questions: (1) Can this be done with python? If so, what module do I need to look up? (2) If it can't be done with python, is there some small utility that will do it for me? Something I could easily install locally in my own "public_html" dir on my website? (3) Is this the sort of thing which, if done regularly, would hog far far too much of my webhosts system resources? (4) Am I talking about re inventing the wheel? -- http://mail.python.org/mailman/listinfo/python-list
