#front-end performance

#122 patch did not fix the issue for our page that's hosted on aws and we're getting 403 from the server. To make it harder to debug, the media library pagination works locally and on our CI.

I was thinking about writing an http_middleware that is checking the request size and creates a watchdog warning if request is to big. Then at least we'd know we're going to have problems on production environments.

This is how our request looks like:

GET /views/ajax?media_library_opener_id=media_library.opener.editor&media_library_allowed_types%5B0%5D=image&media_library_allowed_types%5Bdocument%5D=document&media_library_allowed_types%5Bgallery%5D=gallery&media_library_allowed_types%5Bvideo%5D=video&media_library_selected_type=image&media_library_remaining=1&media_library_opener_parameters%5Bfilter_format_id%5D=restricted_html&media_library_opener_parameters%5Btenant%5D=<id>&media_library_view=media_library&media_library_display=widget_table&hash=<hash>&_wrapper_format=drupal_modal&_wrapper_format=drupal_ajax&view_name=media_library&view_display_id=widget_table&view_args=image&view_path=%2Fmedia-library&view_base_path=admin%2Fcontent%2Fmedia-widget-table&view_dom_id=d9cf4f37403929685b2da3338f20b4af842d6a45f430e626c1acfaa79e4abc69&pager_element=0&media_library_opener_id=media_library.opener.editor&media_library_allowed_types%5B0%5D=image&media_library_allowed_types%5Bdocument%5D=document&media_library_allowed_types%5Bgallery%5D=gallery&media_library_allowed_types%5Bvideo%5D=video&media_library_selected_type=image&media_library_remaining=1&media_library_opener_parameters%5Bfilter_format_id%5D=restricted_html&media_library_opener_parameters%5Btenant%5D=<id>&media_library_view=media_library&media_library_display=widget_table&hash=<hash>&_wrapper_format=drupal_modal&page=1&_drupal_ajax=1&ajax_page_state%5Btheme%5D=<theme>&ajax_page_state%5Btheme_token%5D=<token>Q&ajax_page_state%5Blibraries%5D=<924chars-of-hash> HTTP/2
