I have a website where I need to change the URL structure. The old URLs look like
/olddir/part1_de.htm, the new ones will look like
/newdir/sub/category/anotherpage.htm. There are a lot of URL rewrites I need to do, I assume about 500 distinct rewrites in the end.
As my website gets quite a lot of traffic, my main concern is about performance at the moment. My questions are:
- I assume that for each request, the rewrites block will be parsed and the regex will be evaluated. Am I right?
- Will there be a performance penalty if I use these rewrites? Can nginx handle this?
- Are there any "best practices" to follow when doing a lot of rewrites?
