Package: apache2-mpm-prefork
Version: 2.2.16-6+squeeze1

As of version 2.2.16, Apache applies a fixed line length limit of 8192
bytes when talking to a CGI script: in file `server/util_script.c`,
function `ap_scan_script_header_err_core`, at lines 403--433,
one can read:

        char x[MAX_STRING_LEN];
        char *w, *l;
        [...]
        if (buffer) {
            *buffer = '\0';
        }
        w = buffer ? buffer : x;
        [...]
        while (1) {
            int rv = (*getsfunc) (w, MAX_STRING_LEN - 1, getsfunc_data);

where `MAX_STRING_LEN` is defined in `httpd.h` to be equal to
`HUGE_STRING_LEN`, that is, 8192.

The directive `LimitRequestLine` should apply here as well, or the
documentation should make it clear that this setting does not
influence the CGI module.

I'm using Debian squeeze, with the latest updates:

    $ dpkg -l apache\* | grep ^i

Documentation has been fixed:

git diff debian/2.2.21-5 debian/2.2.22-1 docs/manual/mod/core.html.en
     <div class="note">Under normal conditions, the value should not be changed from
-    the default.</div>
+    the default. Also, you can't set this higher than 8190 without
+    modifying the source code and rebuilding.</div>

Thank you
