That's an interesting configuration. For a while Ive been considering a solution based on longer-than-usual chains of http proxies, and a "do one thing well" principal.

[You should be able to find several references to this in the archives.] Firstly, these old XXXUserFolder products still work acceptably unless you are using the PTK (or other similar products). The incompatability is not with Zope, but rather with these other products. Adding to NUserFolder to keep up with API changes is probably not the best solution, because the User Folder API has been significantly extened. A better approach is to use a customisable User Folder product like LoginManager. It should be possible to transplant the authentication functions from NTUserFolder.

For example, the following from Netscape ... (it happens >with both IE and Netscape on many platforms I have tried ... Mac, all >Windows, and Linux). Yes, this is indeed a problem. I have developed some patches to support Unicode in ZPublisher which uses a technique where the character encoding is added to the form field name (where ZPublisher already expects other marshalling information) For example if you have a form with fields named... address:string age:int ...you would change those to... address:utf8:string age:utf8:int if you are expecting your form response to be submitted in utf8. Under this patch, you could also change that field to. address:utf8:ustring and store your addresses in unicode. It is possible to guess what character encoding will be used in a form response. The situation isnt quite as simple as Dieter Maurer suggested, but the rules (as I understand them from experimentation) are in the release notes for this patch.

Any opinions on this? For a machine of that size I suggest you use only one publisher thread (thats -T 1 on the command line), rather than the default of 4.

Tackling this deficiency is on my to-do list too, but I wont be upset if someone else does the work first. API changes in 2.2 (and future developments, like PTK) make custom user folders less attractive than they used to be. If you intend committing some time to this then I recommend something based on http://www.zope.org/Members/tsarna/LoginManager The simplest change would be to transplant the authentication code out of (jc)NTUserFolder and into LoginManager methods. However that would still only run on NT. A solution that runs on linux and solaris only is oulined at http://www.zope.org/Members/tseaver/LoginManager_and_SMB.

Not quite. That permission controls several methods that are particularly useful for FTP (indeed, you cant do FTP without them). However you could also call those methods using xml-rpc, soap, or ZPublisher (or, not, depending on the whether you have the 'FTP access' permission). Your suggestion makes sense for WebDAV which, like FTP, only uses a small set of methods. I dont think its appropriate for a more flexible protocol like xml-rpc, soap, or ZPublisher. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Zope already has a perfectly good definition of 'web service' - the definition used by ZPublisher and the xml-rpc implementation (and FTP, to a lesser extent). Developing Zope services already involves enough detail - An extra layer of abstraction here is undesirable. I suspect many people using xml-rpc are, like me, not completely satisfied with its feature set. Id been looking to soap to fill these holes, and I would be disappointed if soap wasnt implemented in the same way. >Some attention should be given to how SOAP services get exposed by >other systems at this point (they do *not* just suddenly expose >every in-memory object to SOAP).

Lazy searching is not an issue - that definitely happens. The catalog always uses its cached metadata for searching and sorting. A more interesting question is over sorting-by-index. Whether or not this happens depends on the relative size of two sets: a. The number of *different* *values* for the sort attribute over the whole catalog content. b. The number of matches found. If number(b)>number(a) then sorting-by-index works well. This might happen for example if you are sorting by "author name", where there are more matches than there are authors. This is efficient since the catalog precomputes the matches grouped by author name, and it only needs to sort the groups.

Ill fill in some more details about the fictional example for which I still can't see an easy solution Zope is used to store books. Each book object contains: 1. The text of the books, each page in a separate object 2. Images and diagrams for the book. 3. A ZCatalog full-text-index of the book. Each book object allows: 1. Searching, viewing pages, etc. 2. Dynamically rendering a range of pages as pdf, postscript, etc. The whole database stores 10,000 books, and is served by a cluster of many identical Zope servers. A typical usage pattern might be: a. Users searches through a book to find the interesting pages b. He browses the pdf version of those pages c. He tweaks the page range, and double-checks the pdf version. d. then downloads a postscript version of that page range for printing Assume that noone has accessed this book recently, so it's not in any caches. The cache has to be filled at step b. This transfers alot of data - possibly the whole content of the book - and introduces a noticeable delay. The possibility for optimisation comes at steps c and d. There is one cache already filled with the right data - if the requests from c and d can be directed to the same server as the original then the cache-filling delay can be avoided. This extra delay might not have a great impact of actual site performance, but I've found a catastrophic affect on perceived performance in some usability tests. Users seem happy to accept a delay when they first access their data, but not if it repeated in a subsequent request. Bill wrote... > http://my.site.com/sec1 is mapped to: sec1.site.com, which > is load balanced across as many machines as possible I might be reading more into his words than was intended, but I think this demonstrates the problem.

Suppose your zope site www.contrived-example.com is comprised of many largely independant sections, http://www.contrived-example.com/section1, http://www.contrived-example.com/section2 etc. Your multiple Zopes can all serve all of these sections, however theres not enough storage for each machine to hold all the sections simultaneously. You can make better use of ZODB's in-memory cache and the ZEO pickle cache if the requests for /section1 usually go to the same server. However, you don't want to hardwire this relationship since any other machine should handle /section1 if its 'home' machine goes down, or is busy.

These products that cache stuff internal to Zope are great if you need zope to process the cached data (from your desciption, you dont) If you need to cache whole requests, then the best approach is to understand and use the http cache headers.

LocalFS happily uses the If-Modified-Since header, so an http cache (I use Squid, http://www.squid-cache.org/) can cache LocalFS content outside of Zope.
