process_response()

@classmethod
def process_response(
    request: [HttpRequest](../../http/request/httprequest.md?sid=django_http_request_httprequest),
    response: [HttpResponse](../../http/response/httpresponse.md?sid=django_http_response_httpresponse)
) - > [HttpResponse](../../http/response/httpresponse.md?sid=django_http_response_httpresponse)

Compresses the HTTP response content using gzip if the client supports it and the content meets size and encoding criteria. It updates the 'Vary', 'Content-Encoding', and 'Content-Length' headers, and weakens any existing strong ETags to comply with RFC 9110.

Parameters

Name	Type	Description
request	[HttpRequest](../../http/request/httprequest.md?sid=django_http_request_httprequest)	The incoming HTTP request object used to check for 'Accept-Encoding' support.
response	[HttpResponse](../../http/response/httpresponse.md?sid=django_http_response_httpresponse)	The outgoing HTTP response object to be evaluated for compression.

Returns

Type	Description
[HttpResponse](../../http/response/httpresponse.md?sid=django_http_response_httpresponse)	The original or gzipped response object with updated headers and content.
