The mod_rewrites encoding can be changed with option 'noescape|NE' (no URI escaping of output)
This flag keeps mod_rewrite from applying the usual URI escaping rules to the result of a rewrite. Ordinarily, special characters (such as '%', '$', ';', and so on) will be escaped into their hexcode equivalents ('%25', '%24', and '%3B', respectively); this flag prevents this from being done. This allows percent symbols to appear in the output, as in RewriteRule /foo/(.*) /bar?arg=P1\%3d$1 [R,NE] Rgds, Fred Michael Böckling wrote: > > >> why aren't you >> switching to https before it gets complicated, i.e. when a simple request >> is coming in, like for the form page itself? > > Unfortunately, that is not an option. > > >> - is the Location header apache httpd sends back for the >> redirect still >> OK?
