Moritz: Ok, this topic has not directly to do with Tcl but may very well be important for some Tcl developers who have to program a website in Tcl. LV What is your definition of web publishing? Do you mean publishing books on the web? Or do you mean making web pages available on a server? Or something else?
One good online resource is the online book "Philip and Alex's Guide to Web Publishing" [L1 ] by Philip Greenspun. Btw, Mr. Greenspun uses Tcl and Oracle for website development and has created large websites in Tcl (I'll add links soon).
