Re: [naviserver-devel] default filename extension

[Jeff R. <dv...@di...>]

There's no builtin way I know of to define a default extension.  I would 
do this with a preauth filter, something like this:

=== default_extension.tcl ===
ns_log notice "Loading default extension"

proc default_extension {why} {
     set url [ns_conn url]
     # set loglvl notice
     set loglvl debug
     ns_log $loglvl "default_extension url: $url"
     set file [ns_url2file $url]
     ns_log $loglvl "default_extension file: $file"
     if {![file exists $file]} {
         if {[file exists $file.adp]} {
             ns_log $loglvl "adp extension for $file found"
             ns_internalredirect $url.adp
         } elseif {[file exists $file.html]} {
             ns_log $loglvl "html extension for $file found"
             ns_internalredirect $url.html
         } else {
             ns_log $loglvl "no default extension for $file found"
            # will just fall through
         }
     }
     return filter_ok
}

ns_register_filter preauth * * default_extension

ns_log notice "Loaded default extension"

=== cut here ===


You could also implement similar logic in a url2file handler.

Maybe this is something generally useful enough (something like apache 
MultiViews) to include as a default module, although in that case it 
would make sense to make it configurable from the config file.
