Re: [Zope-dev] RAMCacheManager and gzip
I think I have figured out what I did wrong, but I now have compression working for IE That's great! I was recently noticing that some web pages saved locally from within Mozilla were gzipped, so this thing is moderately widespread. I think it would be a great addition to Zope. Particularly useful with all those blank lines in Page Templates' output. ;^) If anyone wants the patch to play with, drop me a line (It's a file to add to the PatchKit folder. PatchKit auto-loads all patches it finds - just restart Zope, or refresh PatchKit). Yes, please, send it my way too. Time's also ripe to give a glance to PatchKit. -- Mozilla will be around long after nobody can remember just quite what Internet Explorer actually used to be.

Re: [Zope-dev] RAMCacheManager and gzip
Ok, that was my though, so I have uninstalled IE6, just incase the install was broken, and I will do some more testing tonight. I really need to put this to one side in favour of another caching problem I have been asked to look at though. I will probably pick it up again in a day or two.

Re: [Zope-dev] RAMCacheManager and gzip
Ok, I stand corrected (and with egg on my face for abusing zlib). The moral of the story is that zlib.compress(data) is NOT the same as gzip data browser (Which I guess I should have known). Thanks for the pointer Jan!

Re: [Zope-dev] RAMCacheManager and gzip
Just to let you know, I am looking at patching ZServer using my PatchKit
product to do Content-Encoding: ... stuff... anyone interested in testing
when I get it running?
(Probably a couple of days before I get a running version...)

Subject: [Zope-dev] RAMCacheManager and gzip
Hi,
Is it possible to marry the RAMCacheManager and gzip?
I'm just working on a little shop and - for speed's sake - do 'ram-cache'
the article-listings and push all the Zope-Content through mod_gzip. With
this combination, I'm getting it 3x faster in Zope and 5x faster over the
wire (normally 64k). That's great so far. But I don't see any sense in
zipping cached content over and over, so I tried to zip the cached data in
RAMCacheManager. In my first attempt, i replaced:
ZCache_get (RAMCacheManager.py):
entry.access_count = entry.access_count + 1
return entry.data
with:
entry.access_count = entry.access_count + 1
ob.REQUEST.RESPONSE.setHeader('Content-Encoding','compress')
return zlib.compress(entry.data)
The results:
1.
This works with Mozilla 0.96 only for very small entry.data. When I set
entry.data to 'XX', it works, but any real page gets
'htmlbody/html/body' as the result.
2.
This doesn't seem work in IE alltogether. (with 'Content-Encoding: gzip' -
zlib.compress != gzip!?)
I'm willing to spend some days of work for this feature, but although I
have
2 years experience in Python I'm quite new to Zope and Internet-RFC's
and this is definitely a point, where I would appreciate some hints from
more experienced Zope-programmers (or a product, of course -- or the
statement, that this won't be possible... ;o)
regards
Jan Stiller
P.S. sorry, if my words seems a bit confused, I'm more used to reading
than
writing english...

[...] IMNSHO, mod_gzip does (can do) caching on its own (directives mod_gzip_keep_workfiles and mod_gzip_temp_dir), and perhaps it might work with mod_proxy in some intelligent way. Maybe you might want to check this first before doing too much work. Also be warned, there are certain kinds of documents which will make problems when served compressed, like PDFs. While you won't want to RAM-cached PDFs, it might occur that RAM-caching and compressing do conflict. cheers, oliver ___ 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 )
