I''m not too versed on source code so forgive the ignorance. May I conclude from the following that the httpsd included in secureweb-3.0-1.rpm was based on Apache 1.3.9? [root@melanie /root]# grep VERSION /usr/include/apache/* /usr/include/apache/ap_mmn.h: * 19980304 (1.3b6-dev) - abstraction of SERVER_BUILT and SERVER_VERSION [...] /usr/include/apache/httpd.h:#define SERVER_BASEVERSION "Apache/1.3.9" /* SEE COMMENTS ABOVE */ [...] If I wanted to compile my own mod_perl, could I safely use the source code available at Apache.org for 1.3.9? Has anyone else had problems with perl/mod_perl/"RedHat Secure Web Server" version mismatches? John Walker
