Debug ASP with IIS (original)

Debug ASP with IIS (original)

It is often seen that the user raises an HTTP 500 error and does not know where the error is. A simple method is provided.

Prerequisites:

1. set the site where IIS is to be debugged. In the site property => main directory => Configuration => application debugging bar, make sure to send the detailed ASP error message to the customer (s) an item is selected.

2. Set Internet Options for IE => advanced => remove the friendly HTTP error message.

When a 500 error occurs, you can use an unrecoverable Text Editor (such as commonly used Dreamweaver and editplus) to remove all your ASP source code, write a few words at will, and save it (do not exit ), refresh your page .. there should be no errors at this time. Switch to the editing page, undo the previous action, save it, and refresh again... the detailed error message (error line, details) appears ).
