Hi,
After i did my unusable proxy patch for multiple brigade handling by
mod_cache, i tried to patch the mod_cache.
My code is doing:
receiving one brigade
if EOS inside, cache it and cache cache-saved_brigade if not null.
if no EOS, save brigade in cache-saved_brigade
w8 for another brigade, until EOS inside.
This code is working,
I controlled the data written in the cache and his length.
But i have a bug, and i really don't understand why
When i call manual.css (2 brigades) alone
http://127.0.0.1/manual/style/css/manual.css:
first time, it's cached by the mod_cache and served by proxy
second time, it's served by cache
data received are the same, i did a MD5 on it !
that's why i think the code is working.
When i call http://127.0.0.1/manual which is using manual.css, the same
as above:
first time, it's cached by mod_cache and served by proxy
second time, the manual.css is not used by the browser. (netscape US
langage)
i sniffed the connection btw the reverse proxy and the client.
the manual.css data are sent correctly to the client, but there is a
difference btw:
served by proxy: HTTP/1.1 and no keep alive
served by cache: HTTP/1.1 and keepalive + content-length. and age=value
the others headers_out are the same.
I will continue to search why this bug is happening.
I insert my code as attachment, sorry for the french comment inside if left.
