[RESOLVED] Limit to number of Rewrite Rules?

gwerner

The title pretty much sums it up. Is there a limit or any kind of performance issue with doing what I'm doing below? Total number of rewrites when all said and done might be a couple hundred. Until I learn more about OOP, I'm using a simple page front controller to serve pages on a site I'm building.

This is not a eCommerce site, so there is no shopping cart or anything like that. So there won't be thousands of products. The product pages are simply feature listings of each product that belong to a product category. Each category might have four or five products and those products might have a dozen or so feature pages.

This is what my URLs look like behind the scenes.

/productCategory/index.php?page=product1
/productCategory/index.php?page=product2
/productCategory/index.php?page=product3

etc..

/productCategory/index.php?page=product1Feature1
/productCategory/index.php?page=product1Feature2
/productCategory/index.php?page=product1Feature3

etc..

This is what I'm using mod_rewrite to accomplish.

/productCategory/product1/
/productCategory/product2/
/productCategory/product3/

/productCategory/product1Feature1.html
/productCategory/product1Feature2.html
/productCategory/product1Feature3.html

I'm changing the product page to a directory and replacing the php with html.

A rule of thumb I came across once: "If you have to ask if there are limits, you might be going about things the wrong way."

In this case, there is the Alias directive if you want to stick with a big long list of aliases that need to be maintained.

Or there is the RewriteMap.

Or if the URLs are consistently-enough formed (e.g. "anything that looks like [font=monospace]/productCategory/xxxxx[/font]") then mod_rewrite can do pattern matching.

But to answer your specific question:

The mod_rewrite documentation wrote:
It supports an unlimited number of rules and an unlimited number of attached rule conditions for each rule, to provide a really flexible and powerful URL manipulation mechanism.

Why on earth would you write a couple hundred rewrites when only a couple (literally - only 2 from your post above) will do?

I kinda figured that was the answer I was going to get. I just wanted to be sure. I knew that documentation said unlimited, which added to my confusion. Saying unlimited led me to believe that I could make it as big as I needed, thus forgetting about pattern matching. Whoops.

Thank you sir for your bluntness. : ) This is what I came up with which seems to do the trick for all of it.

RewriteRule ^(.*)/([^/]+).html$ /$1/index.php?page=$2 [NC,L]
RewriteRule ^([^/]+)/?$ /$1/index.php [NC,L]

Thanks again guys.
