--- Begin Message ---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 ii apache2 2.2.16-6+squeeze1 Apache HTTP Server metapackage ii apache2-doc 2.2.16-6+squeeze1 Apache HTTP Server documentation ii apache2-mpm-prefork 2.2.16-6+squeeze1 Apache HTTP Server - traditional non-threaded model ii apache2-utils 2.2.16-6+squeeze1 utility programs for webservers ii apache2.2-bin 2.2.16-6+squeeze1 Apache HTTP Server common binary files ii apache2.2-common 2.2.16-6+squeeze1 Apache HTTP Server common files Thanks, Riccardo
