The FYI I left others in my org. should explain every thing in context better than a diatribe from me. After that is the text/* segment of our mime.types file.
ServerName www.musicyellowpages.com AddType text/x-server-parsed-html .shtml AddType application/x-httpd-cgi .cgi AddType application/x-httpd-cgi .pl AddType text/x-server-parsed-html .html AddType text/x-server-parsed-html .htm AddType text/x-server-parsed-html .inc ExpiresActive on ExpiresByType application/x-httpd-cgi A120 ExpiresByType text/x-server-parsed-html "access plus 120 seconds" # Doesn't work # ExpiresByType text/html A120 ###FYI undocumented quirk: mod_expires uses the initial mime/type for the # file and not the served mime/type. ie; since we are using *.htm # in place of *.shtml, our internal mime/type is parsed (via addtype) # however the output is just text/html since this is derived from the # file mime.types # In other words AddType overrides mime.types declarations when dealing # with a file internally yet fails to override those declarations in # the header sent to the client. mod_expires doesn't pull mime/types from # mime.types or at least not until it has checked the current env. for # AddType declarations. ExpiresByType text/html A120 # OK, it works but not on *.htm, *.html, *.inc, *.cgi, and *.pl exts. # Maybe, we should use *.shtml for static pages # Header append Cache-Control must-revalidate # mime.types file segment text/html html htm text/x-sgml sgml sgm text/plain txt text/richtext rtx text/tab-separated-values tsv text/x-setext etx >How-To-Repeat: use *.htm and *.html as a text/server-parsed-html mime/type using AddType directive as above. Then use ExpiresByType text/html A###. The output headers will show Content-Type: text/html but no Expires: header. >Fix: Just document it with the mod_expires directives and if this is more serious than I think it is, put it onto the "Maybe Tommorrow, TODO list". >Audit-Trail: >Unformatted: [In order for any reply to be added to the PR database, ] [you need to include <[EMAIL PROTECTED]> in the Cc line ] [and leave the subject line UNCHANGED.
