Webware for Python

OK,
I did not read your post carefully.

I looked in Request().serverDictionary()
from WebKit.Page import Page
class test(Page):
    def writeHTML(self):
        self.response().addHeader('content-type','text/plain')
        for key in self.request().serverDictionary().keys():
            self.write("%s => %s\n" % 
(key,self.request().serverDictionary()[key]))

but did not see anything useful.  It may not be passed by the adapter.

Yep; there doesn't seem to be anything there, except some of the more common 
headers (user agent, client IP, etc).

Correction; it seems that *sometimes* (I cannot quite replicate this 
consistently) I can get an HTTP_IF_NOT_MATCH variable in the environ() dict. 
  To get this, I have to put an "ETag" header on a prior response, but I 
don't consistently get it back.  I.e.:

Request_1: Client requests a WK Page.  No ETag/Last-Modified header
Response_1: WK sends back an ETag/Last-Modified header in the response
Request_2: The client sends the If-Not-Match/If-Not-Modified-Since headers 
that correspond to Response_1's headers.  However, I only get the 
If-Not-Match header in self.request().environ() dict only intermittently.

I think it could be that Apache may be intervening in Response_1, trying to 
enforce the ETag.  Actually, I think the WK adapters are a bit buggy here...

Well, I have tested this on the CGI adapter on XP (with apache) and on 
mod_webkit2 on RHL.  Same behavior.

Thanks,
