[users@httpd] make URL's case insensitive
Hi All,
I run apache 2.0.5x, and was wondering if there is a way to make URL's (after
the domain portion) case insensitive in apache (all URL's), for example:
www.foobar.com/JUNKFOOD.htm (client browser)
would be processed by httpd as:
www.foobar.com/junkfood.htm (server side)
In reading the apache FAQ in 1.3, it says the following:
You can't! The reasons are: first, that, case translations for arbitrary length
URLs cannot be done via regex patterns and corresponding substitutions. One
needs a per-character pattern like the sed/Perl tr|..|..| feature. Second, just
making URLs always upper or lower case does not solve the whole problem of
case-INSENSITIVE URLs, because URLs actually have to be rewritten to the correct
case-variant for the file residing on the filesystem in order to allow Apache to
access the file. And the Unix filesystem is always case-SENSITIVE.
But there is a module named mod_speling.c in the Apache distribution. Try this
module to help correct people who use mis-cased URLs.
Barring this, can mod_speling be set to not provide a list of files that are a
'close match' providing that the exact match is not found?

Apache doesn't matter here. Neither does the underlying operating system
or filesystem.
It is HTTP, the protocol of the Web, that is case-sensitive.
Anything that tries to pretend it's not is broken.

Well, you just changed your question. Mapping to all-lowercase is
actually possible, as opposed to general case-insensitivity which is
not possible (and, in addition, not advisable, since proxy caches,
search engines, etc are all case sensitive).
Something like:
RewriteEngine On
RewriteMap lc int:tolower
RewriteRule (.*) ${lc:$1} [R]
(The [R] on the end is not strictly necessary, but is highly
recommended unless you want many variants of your URLs to propogate to
search engines and caches.)

Well, the goal is to simply make everything in the URL which is received by
APACHE lower case, as case sensitivity is a(n) issue on unix/linux/etc. In
windows it doesn't matter, since filenames are case insensitive (hope that
clears up the confusion)...

Barring what? Your question is not very clear. What about the answer
in the FAQ didn't you understand? (If you are asking if this has
changed in 2.x, the answer is no.) Regarding mod_speling, no it is
not possible to turn off the Multiple Choices page (without hacking
the source code). You could try
ErrorDocument 300 http://example.com/404.html
but I don't know if that would work.

Use mod_speling

What about creating a 404 cgi error document that will present the user with a
message saying "Did you mean www.foobar.com/junkfood.htm" That way, they
will find the file, and be reminded about the spelling for the next time.
