# Request URL Limitations

## Hard Limits

- **Total Request Size**: The Qwilt CDN supports request URLs encompassing the complete aggregate of the URI, query parameters, and headers, with a limit of 32KB.
- **Request URI Size**: The request URI cannot exceed 8KB.
- **Header Size**: Combined header size cannot exceed 8KB.

**Errors:**

- A request that exceeds the Request URI Size limit is rejected and returns a *414 Request-URI Too Large* error.
- A request that exceeds the Total Request Size limit or the Header Size limit is rejected and returns a *400 Bad Request* error.

## Soft Limit

The maximum allowed number of request headers is 100. This limit will not generate an error. Headers beyond the limit of 100 are ignored.
