There's mod_deflate module for Apache 1.3.x that patches buff.c and
compesses a response on the fly. It's available at http://sysoev.ru/en/

Content-Encoding: gzip header.
My mod_deflate allows optionally to add Vary header to compressed
response only.

Actually, with MSIE 5.5+ appearance the chances that client can not
decompress the response from downstream cache have increased.
If MSIE 5.5 is configured to work via proxy with HTTP/1.0, then
MSIE will never send Accept-Encoding

No, just look at http://sysoev.ru/mod_accel/
It's Apache 1.3 module as you need.

What was the reason for disabling https proxying caching ?
How do you think to do https reverse proxying ?

I'll be more then glad to discuss it with you.
So proxy should decrypt the stream, find URI, then encrypt it, and
pass it encrypted to backend ?

the answer to the client
of course after caching it.
Well, it's the same as I described.
No, mod_accel can not connect to backend using https.

sat down to look at the
relevant RFCs. It might be easy, but it might be hard.
MSIE, Mozilla and Opera do not understand RFC 1950 'deflate' method, i.e.
they want RFC 1951 only deflated stream without any zlib header
and Adler32 checksum trailer.

that zlib required for compressing - 256K-384K.
So I have directive to disable a compressing to avoid an intensive swapping
if a number of Apache processes is bigger then specified.

is in Russian only. Sorry.
Some features:
It patches Apache 1.3.x so it allows to compress content without
temporary files as mod_gzip does. It allows two encoding - gzip
and deflate. It has some workarounds for buggy browsers.
On FreeBSD it can check CPU idle to disable compression.

application/msword when compressed. NN and Opera does not.

Er, mod_proxy _was_ a very ancient module, but has been largely
overhauled in v1.3 and completely rewritten in v2.0 in both cases having
full support of HTTP/1.1

But ap_proxy_send_fb() flushes output to client so it can hang

I have come up with a patch to solve this problem - in theory anyway

mod_rewrite can not do it.
Then rewrite should be patched to do it.
Your phrase is like 'mod_rewrite should be patched to do some SSI job'
mod_rewrite works with URLs and filenames only. It can not change content.
mod_randban changes content on the fly.

No. mod_proxy tries it but code is broken. If connection failed it try

Don't know if those cases would be seen by Solaris users of Apache
