如果标题中的Content-Type是text / html，则重新加载图像

Question

I have image generator that sometimes fails and sends a error in text/html while the Status is still 200.

What is the best way to reload the image from the same url if the content-type is not image/jpeg. Should I approach this in a separate php file with curl headers and reload if it's not image/jpeg or is it possible to do on client side in javascript/jquery?

Answer 1

You should fix the image generator script to capture exception and try again. At least return status 500 instead.
