It works fine that way, AFAICT, and it's handy if you want to reflect LDAP-like namespaces in a Zope application. And ZLDAPConnection support '=' in path components, so it seems kind of silly for Zope itself not to. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] Cache-bug in handling of files
since all the data at my corporate intranet site is pulled from a RDMS, all my refrence URLS are generated in JavaScript and have a rnd="a randomly generated number between 1 and a million" to force the browser to get the current page. __ Jim Sanford .

I set my cache to "Automatically" like yours and restarted it. I then opened a Netscape and created a new file object. I instrumented the code in the 'index_html' method of File objects so that I could tell _for sure_ whether things were actually being called at the server or not. Here's what I did: - create a file 'myfile.txt', uploading a contents of text1.txt into it. - visit the view tab with IE. The server confirms that the index_html was called, and the whole content was sent, not a 304. - now (using netscape again) upload the contents of text2.txt into the file object. The mgmt screen correctly shows the updated byte length, etc. - click the 'view' tab again on IE. My instrumenting confirms that IE is not contacting the server *at all* no matter how many times I click the 'view' tab, and I keep seeing the old content. A look at the headers produced by this shows nothing that tells IE it should be doing that: HTTP/1.1 200 OK Server: Zope/(unreleased version) ZServer/1.1b1 Date: Fri, 11 Aug 2000 15:18:50 GMT Connection: close Content-Type: text/plain Content-Length: 944 Last-Modified: Fri, 11 Aug 2000 15:16:06 GMT Interestingly, if you open the "view" tab in a new window, you'll see the updated content. Now, using that same new window, set your cursor at the end of the url string in the url bar and hit return. IE seems to reload the page, but it is not actually even contacting the server. Stranger yet, if you click the "refresh" button it *will* contact the server (and it passes an If-Modified-Since header, and correctly gets a 304 Not Modified). Now, use netscape to change the content again. The whole thing starts over. Clicking the 'view' link on the page or pressing return in the URL bar will not even contact the server and the only way to get the updated content is to explicitly press "refresh" or open a new window, even though the resource returned no caching information one way or the other. I'm going to close that bug report and include this report for those who may find it useful in the future.

This bug report was related to the fact that the user was accessing the file through a Squid cache and that at the time (Zope 2.0.1) there was a legitimate bug in the way that "If-Modified-Since" headers were handled. Squid was actually returning the file to him. It should have been marked completed quite a while ago (I just did that). I am using IE 5 (5.00.2314.1003), cache settings set to: "Check for newer versions of stored pages: x Every visit to the page ...and I cannot reproduce the problem that you are describing :( Are these your cache settings? Are you accessing the server through any kind of proxy?
