[Bug 54050] New: Debug info forgotten in code gets mixed with HTTP content.

https://issues.apache.org/bugzilla/show_bug.cgi?id=54050

          Priority: P2
            Bug ID: 54050
          Assignee: bugs@httpd.apache.org
           Summary: Debug info forgotten in code gets mixed with HTTP
                    content.
          Severity: normal
    Classification: Unclassified
                OS: Linux
          Reporter: dveiga@advtechnology.com.ar
          Hardware: PC
            Status: NEW
           Version: 2.2.22
         Component: mod_proxy
           Product: Apache httpd-2

I use mod_proxy to expose an internal site (IIS) to the internet. The HTTP
content sent to the internet is not exactly the same as the content received
from the internal site. It has some strings added (by 'added' I'm precise, the
content is not overwritten, theese strings are added at certain points in the
middle of the actual HTTP code). I believe they are debug info because I'm a
programmer and its the type of code you add to trace a bug. The strings are:
1) Always the same for a certain input.
2) Always inserted in the same place.
3) Always inserted (100% reproduceable).
Sample strings are '13', '38a', '80' and 'f6'.
I'm sure its an Apache problem because I used Wireshark on the server to
capture input and output streams in an HTTP (clear text) connection and they
differ. Help offered to debug/test.

--- Comment #1 from Jeff Trawick <tr...@apache.org> ---
That sounds like hex lengths for chunked encoding in the response.
HTTP/1.1 request from client with "Transfer-Encoding: chunked" in the response
from httpd?  Are those hex strings the length of the following data?

What is the problem symptom in the client?

You're right. I'm embarased and apologize for wasting your time. I didn't know
