# i convert cgi styled URLs into static like following:

RewriteCond %{QUERY_STRING} s=([^&]*)&lng=([^&]*)
RewriteRule ^/searchform /a/%2/%1? [R=301]

# everything is OK until space symbol is used in the value.
# the space symbol for some bloody reason is encoded not as %20, but as '+'
# and from the URL
#
#   mysite.com/searchform?s=depeche+mode&lng=en 
#
# i become:
#   mysite.com/a/en/depeche+mode
#
# instead of:
#   mysite.com/a/en/depeche%20mode
#
# how could I get %20 ?
#
# i tried this:

RewriteCond %{QUERY_STRING} (s=[^+]*)\+(.*)
RewriteRule ^/searchform %1%%20%2?[N]
