multipart/mixed html's

[Niels Berkers]

Hi,
i'd like to host my web pages using multiparts to reduce the number of
hits on the server.
i know this isn't a real PHP subject, but i'll try it anyway.
i've been searching the web for solutions and examples with no succes.
does anybody know a good starting point
hints / tips are also welcome

Regards

What are you talking about? Spliting content over multiple pages
eventually with navigation links?

nope,
inline images within te html document. I've got a very high hit rate on
our sites. Due to backward compatebility
to NS4, lots of spacers. I'd like to send this spacer just ones inline,
including all the other images too. So that the communication
to our server is minimized and thus less sockets and apache processes are
needed to serve our customers.

thanks in advance

It's called HTTP persistent connection.

While you are at it, stop using spacers and tables for layout and you
won't have that problem.

i'd like to, but i still have to be compatible with NS4,
which doesn't handle css very well.

Oh, I see. I do have a couple of classes to do that but only one is
published. That one is not quite for embedding images in HTML but rather
in e-mail messages. Still, you can reap the function GetDataURL that
encodes images as it can work alone outside the class. It returns a data
URL that you can use in the SRC attribute of the IMG tag. See the HTML
message sending example to see how it is used.

http://www.phpclasses.org/mimemessage

Anyway, I do think that it is a good solution. I mean I can recommend
you a better one. The problem embeddeding messages in HTML is that not
only it will not work in some browsers, but it also will make your PHP
scripts take longer and consume more memory.

Some time ago I also noticed the problem of having pages with many
images making Apache fork to many processes during a peak. What I did is
to make the images be served from a separate domain or port by an HTTP
server dedicated to serving static content.

The static content server that I used is thttpd . It is multithreaded,
so it takes much less time to serve static content from files like it is
the case of images. It works either on Unix/Linux and Windows.

All I can tell you is that the results were fantastic. I used to have
more than 100 Apache processes in average and during peaks it would blow
my server memory. Now, with thttpd serving just static content, Apache
rarely raises over 30 simultaneous processes and thttpd itself uses less
than 1.5MB of memory when running.

Re: multipart/mixed html's

Thanks Manuel,
you've been of great help,
you're right, composing multiparted html's might not be the solution to my
problem.
reducing load on the server by serving static content thru a tiny http
server, seems
to be de most logical solution. But still, it would be awesome, to serve
multiparted
files. 8-) a project for the free hours 8-)

What I first explained was not really using multipart pages but rather
embedding image data in HTML IMG tags. The class that I mentioned can
also compose multipart data. I think the correct name is multipart
related HTML (AKA MHTML) and not multipart/mixed as you mentioned.

multipart/related is for bundling related parts into the same body
(page, images, style sheets, frames, etc...). multipart/mixed is for
attaching files to messages but they are parts not related and may be
displayed independently.

I predict this is your next problem. I don't think, NS4 is able to handle
multipart-, mime-encoded html-documents. But Im not sure though. I haven't
messed with those yet.

[Niels Berkers]

Re: multipart/mixed html's

Hi Manuel,
you're right again!
surfing around / reading rfc's the correct mime would indeed be
multipart/related

ok kowning this : does anyone has an een working example of a
multipart/related page generated with PHP.
The code can be totally exotic / a mess -> just for starting
or even better a class which could do this ? The class Manuel suggested has
the functionality for creating the body, but it's missing the functionality
for sending it to the
browser ( because it an email class)

I don't see a problem. All the spacers should just be a single file
(spacer.gif or whatever) with different width and height attributes in
the HTML. Every visitor generates just one hit on the server for all
spacers.

Have you perhaps gone and created dozens of differently sized spacer
GIFs? Or have you perhaps done something which suppresses caching? I'd
look in those directions first.

In any case, with Netscape 4 usage down to somewhere around 1% and still
decreasing, I really wouldn't worry about cosmetics for Netscape 4 users
any more. As long as they can read the pages, that should be enough. (Or
are you at some academic institution that still uses Netscape 4 as its
main browser?) Much better to switch to CSS, and hide those bits of CSS
that NS4 doesn't understand from it. My page
http://www.xs4all.nl/~sbpoley/webmatters/netscape4.html may help.

you're right, when you're talking about a second visit to the page ( or an
other page within the site ) and mod_expires is running
otherwise you still get hits for each spacer 304 ( not modified )
when a page page is first loaded IE still checks for every spacer if it's
changed, expires doesn't work at that point.

nope, i know where i'm talking about. just searching for better solutions

thanks, i'll that a look at that...
i wish i could change over 20.000 pages at ones (maybe much more, i realy
don't know, anyway a lot)

multipart/x-mixed-replace
works fine. I have had a perl script running to serve a webcam stream and it
did work fine.
but how to do this in PHP remains the question
