Apache: Fix get_content_length().
clength in request_rec is for response sizes,
not request body size. It is initialized to 0,
so the "if" branch was never taken.

Log:
BZ 34526: Apache: Improve compatibility with
mod_deflate request body inflation.
An automatic detection of mod_deflate inflation
is not implemented. Allow to use the new Apache
environment variable JK_IGNORE_CL instead, to
let mod_jk ignore an existing Content-Length
request header.
All body data that can be read from the web server
will be send to the backend. No Content-Length
header will be send to the backend.

[Bug 34526] Truncated content in decompressed requests from mod_deflate
https://issues.apache.org/bugzilla/show_bug.cgi?id=34526 Rainer Jung changed: What|Removed |Added Status|REOPENED|RESOLVED Resolution|--- |FIXED --- Comment #14 from Rainer Jung --- The situation has been improved in r1649064. Unfortunately it doesn't seem to be possible to detect request body inflation by mod_deflate before mod_jk actually starts to read the body. Because it needs to send the request headers to the backend before reading the body, there's no easy way to detect the situation. We would need to implement some buffering and change the flow of processing in mod_jk quite a lot. I decided to implement a workaround: you can set the new Apache environment variable JK_IGNORE_CL instead, to tell mod_jk that it should ignore an existing Content-Length request header. All body data that can be read from the web server will then be send to the backend. No Content-Length header will be send to the backend. The environment variable can be set using mod_setenvif or mod_rewrite as usual. You should choose conditions for setting the variable that trigger for the requests, for which you have configured request body inflation by mod_deflate. Setting the variable for other requests as well should work, but might lead to less efficient behavior and maybe also bugs we are not yet aware of. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
