I submitted a form via GET with a large number of text (about 6,000 characters) and received a very long URL error.
I did the same test via POST and the data was sent successfully.
My question is whether there is a data limit to be transmitted via POST, since GET I already know is limited.
In theory, the maximum limit of a post request is unlimited. The actual limit depends on each server application. Matthew has already given the hint how this can be set up in Linux environments (of which I do not understand anything).
For applications running on Microsoft IIS, you set the limit through the IIS dashboard or the web.config file of the application.
I will not dwell here on how to do these settings, but by documentation o default limit of requests is thirty million bytes (approximately 28.6MB ). The maximum configurable limit is 4,294,967,295 bytes, roughly 4GB .
Nodejs already works with a default limit of requests of 80KB (see the HTTP_MAX_HEADER_SIZE variable in source code ). Middlewares such as Connect allow you to set larger limits, but the configurable maximum limit will range from middleware to middleware.
Depends on the server configuration. If you are working with PHP on a Linux or something similar you can control this by setting .htaccess
#Set o tamanho maximo de um post
php_value post_max_size 15M
But if you're using IIS, I have no idea how to do it.
