### Import `HTTPException`

```

### Raise an `HTTPException` in your code

`HTTPException` is a normal Python exception with additional data relevant for APIs.

Because it's a Python exception, you don't `return` it, you `raise` it.

dation~="recaptcha"]',b).each(function(){var d=a(this),e=document.createElement("DIV"),f=c.reCaptchaSiteKey||d.valAttr("recaptcha-sitekey"),g=c.reCaptchaTheme||d.valAttr("recaptcha-theme")||"light",h=c.reCaptchaSize||d.valAttr("recaptcha-size")||"normal",i=c.reCaptchaType||d.valAttr("recaptcha-type")||"image";if(!f)throw new Error("Google reCaptcha site key is required.");var j=grecaptcha.render(e,{sitekey:f,theme:g,size:h,type:i,callback:function(a){b.find('[data-validation~="recaptcha"]').trig...

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

You could also define it as a normal function instead of `async def`:

	MediumBlock = 128 * humanize.KiByte // Default r/w block size for medium sized objects.
	LargeBlock  = 1 * humanize.MiByte   // Default r/w block size for normal objects.
)

// aligned sync.Pool's
var (
	ODirectPoolLarge = sync.Pool{
		New: func() interface{} {
			b := disk.AlignedBlock(LargeBlock)
			return &b
		},
	}
	ODirectPoolMedium = sync.Pool{

A note about ZIP64:

To be backwards compatible the FileHeader has both 32 and 64 bit Size
fields. The 64 bit fields will always contain the correct value and
for normal archives both fields will be the same. For files requiring
the ZIP64 format the 32 bit fields will be 0xffffffff and the 64 bit
fields must be used instead.

   * How is the RateLimiter designed, and why?
   *
   * The primary feature of a RateLimiter is its "stable rate", the maximum rate that it should
   * allow in normal conditions. This is enforced by "throttling" incoming requests as needed. For
   * example, we could compute the appropriate throttle time for an incoming request, and make the
   * calling thread wait for that time.
