How to optimize these config / rewrite rules

[rob]

Hi there,

I'm running nginx and xenforo but need to rewrite some old legacy URL's
(left over from vbulletin + vbseo)..

Here is just a very small selection of my config which I want to
optimise as fully as possible:-
[code]
#Forum 26 main
location = /category-name-73/forum-name-26/  {
    rewrite ^ /forums/forum-name.26/ permanent;
}
 
#Forum 26
location /category-name-73/forum-name-26/ {
    #forum paging
    rewrite ^/category-name-73/forum-name-26/index([\d]+).html
/forums/forum-name.26/page-$1 permanent;
 
    #thread paging (modified version of kier's redirect script)
    rewrite [^/]+/([\d]+)-.+-([\d]+).html /showthread.php?t=$1&page=$2
last;
 
    #thread
    rewrite [^/]+/([\d]+)-.+.html /threads/redirectme.$1/ permanent;
}[/code]

If only I can optimise the above then I can transfer the same principle
to the rest of my (huge) config file.

I've been told that its possible to optimise the above so that a visit
to /category-name-73/forum-name-26/ or any path below it will run just
one regex instead of potentially 4 as per the above code...

So, optimising the above... does anyone have any clue how to do this?

Thank you for any help offered,

Rob
