What are the implications to redirecting images behind the <image> tag?
html, image, redirect
Solution
Another technique that doesn't require a server round-trip is to use your HTTP server's equivalent of a "rewrite engine". This allows you to specify, in the server configuration, that requests for one URL should be satisfied by sending the results for some other URL instead. This is more efficient than telling the browser to "no, go look over there".
Problem
Some setup: We have some static images, publicly available. However, we want to be able to reference these images with alternative URLs in the image tag. So, for example, we have an image with a URL like: ``` http://server.com/images/2/1/account_number/public/assets/images/my_cool_image.jpg ``` And, we want to insert that into our front html as: ``` <img src="http://server.com/image/2/my_cool_image.jpg"> ``` instead of ``` <img src="http://server.com/images/2/1/account_number/public/assets/images/my_cool_image.jpg"> ``` One really neat solution we've come up with is to use 301 redirects. Now, our testing has rendered some pretty neat results (all current generation browsers work), but I am wondering if there are caveats to this approach that I may be missing. EDIT: To clarify, the reason we want to use this approach is that we are also planning on using an external host to serve up resources, and we want to be able to turn this off on occasion. So, perhaps the URL in the would be ``` http://client.com/image/3/cool_image.jpg ``` in addition to the "default" way of accessing
