# ################################################################################################ # I first posted this to zope@zope.org, without success. Although it is not about the development of # Zope itself, it deals with its internals, so now I post it here. # I hope everyone is alright with that. :-) # ################################################################################################ Hi, I would like to show status messages while calling a couple of functions from within a Python Script: While the script is running, I want to successively output messages like ------------------------ Doing this...ok Doing that...ok Done ------------------------ and then either redirect or display a button to move on. 1. I do _not_ want to use JavaScript 2. I do _not_ want to use the meta tag "refresh" I would like to use Response.write() to push my status messages on the fly. Since I don't know which function calls will succeed and which will fail, I do not know "Content-Length" in advance. Therefore, I would like to use a streaming/chunked response as specified in HTTP 1.1. How do I do this in Zope? I tried to do "response.setHeader('Content-Type', 'multipart/x-mixed-replace')" but couldn't get it working. (Also, it looks as if this will only work in Netscape but not IE. True? Then unfortunately I can't go that route anyway.) I also tried to leave the header alone and just "Response.write()" the multipart content-type and its boundary and the content-type's of the parts, but ZPublisher just returned the plain text... I guess the answer lies somewhere in "Transfer-Encoding: chunked" but I can't figure out how to actually do it. :-) Maybe one of you guys working on HTTPResponse.py (Fred, Chris, Brian, Toby, Andreas) knows how to accomplish this? Anyone else? I appreciate the smallest hint. ;-) Thank you very much for your help, Danny P.S.: Please include my address in your reply ("Reply All") since I am currently not subscribed to this list.
