HTTPS 413: The page was not displayed

Problem: User gets an error message when using ArchiOffice/EngineerOffice:

HTTPS 413: The page was not displayed because the request entity is too large.

Solution: This can be resolved in two ways:

1. Request entity body becomes large

- when you upload large file from your web page

- when you submit web page with lot of content

Setting uploadReadAheadSize in applicationHost.config file on IIS7.5 can resolve your issue in both cases. You can modify this value directly in applicationhost.config or use this command

appcmd.exe set config -section:system.webserver/serverruntime/uploadreadaheadsize: 1048576 /commit:apphost

This happens on SSL because during client renegotiation process, the request entity body must be preloaded using SSL preload. SSL preload will use the value of the UploadReadAheadSize metabase property, which is used for ISAPI extensions. For more details, check this article.

2. Access your ArchiOffice application using HTTP:// not HTTPS://
