Form requires disabled prerender

[Lure5134]

I have created a form similar to this example: https://docs.astro.build/en/recipes/build-forms/
After that I was getting the error:
Content-Type was not one of "multipart/form-data" or "application/x-www-form-urlencoded"

Stackoverflow helped me to fix this issue: https://stackoverflow.com/questions/78375098/content-type-was-not-one-of-multipart-form-data-or-application-x-www-form-url

I think it would be helpful to add a help comment similar to: https://docs.astro.build/en/guides/on-demand-rendering/#cookies

export const prerender = false; // Not needed in 'server' mode

Thanks for mentioning this, @Lure5134 . I think this would be a great addition to the recipe! Without checking to confirm, I'm guessing that we did update the requirement to not say "you need output: 'server' (since you don't for our new static/hybrid default), but the rest of the recipe would have been left as it was written when this option did not exist. (So, on-demand rendered pages could be assumed.)

I think what's necessary here is to add that line to every code snippet that shows register.astro, and probably we should explain this in step 1, something maybe like:

Create or identify a .astro page which will contain your form and your handling code. This page must not be prerendered. For example, you could add a registration page:

And then that fits nicely to be shown in the very short code snippet in step one, and it will just carry throughout the rest of the recipe.

I will create an issue from this discussion and label it "help wanted" so anyone can pick this up and make this great improvement! 🙌
