Does HTTP URL parameter order matter for caching? [closed]


Tag: http,caching,seo,uri,url-parameters

Are the two URLs equivalent with respect to browser caching and website seo?

1 -
2 -

If the resource for the first URL is cached and the browser needs to find the resource for the second URL can it use the cached resource? I want to know about the caching because I can ensure all internal links use the same parameter order to increase cache performance.

Also, if my server treats these URLs as the same resource, which URL will be indexed by Google? With consideration to SEO, will this count as duplicate content? If so, I could use a 301 response to redirect to the correct URL. (This should also fix the caching problem.)


If the resource for the first URL is cached and the browser needs to find the resource for the second URL can it use the cached resource?

That is not certain. It depends on each browser implementation. But if you always use the same parameter order, then it is not an issue in the first place.

Also, if my server treats these URLs as the same resource, which URL will be indexed by google?

Both will be indexed by Google, but if you use canonical links or if you configure parameters in Google Webmaster Tools, then they can be treated as one when displaying search results (i.e., Google will give the preference to one URL and it will collect the PageRank and other signals from the other).

With consideration to seo, will this count as duplicate content? If so, I could use a 301 response to redirect to the correct URL.

Yes, it will be considered as duplicate content, because the URLs are different. Using a redirect in this case is shooting flies with a canon (IMHO), but it would work.
