Need HTTP 1.1 support in Tcl , comp.lang.tcl, 2002-01-27
various people discuss 1.1, among other things; Pat summarizes the remarks in .

It seems as if TclSOAP has a proposed version of the http package which supports persistent connection (see above). What else is needed for HTTP 1.1 (and things like the webdav extensions to HTTP 1.1)? Is there a simple overview document which describes in a simple way what the differences really are?

Phil Dietz and Eric Boudaillier have opened a SourceForge project for this with the project name of tclhttp1-1 [L1 ]

PT: Any useful code from the other http1.1 enhanced packages should get merged into this one

tclvfs comes with some minor mods to tclsoap's http package to support webdav -- would be good to merge that stuff.

PT writes: I already did this for the tclSOAP version and I've applied this to the tclhttp1-1 version but I need to commit this (as of 2003-01-27). The tclvfs changes simply add a '-method' option to enable HTTP requests other than GET, HEAD and POST. For instance

set tok [http::geturl -method OPTIONS]

will get the options header from the server. For WebDAV there are a number of other commands to use.
