Web. the config file is a standard xml file. We can use it to set each web application under a machine, an application, or the asp.net page under a directory. Of course, it can also be set for a separate web page.
For example, if the main directory of the website is inetpubwwwroot, we place web. config under it, and the applications in this website will be affected by the settings in web. config.
E.g .:
<? Xml version = "1.0" encoding = "gb2312"?>
<Configuration>
<System. web>
<Compilation defaultlanguage = "vb" debug = "true"/>
<Customerrors mode = "remoteonly" defaultredirect = "js/error.htm">
<Error statuscode = "404" redirect = "js/filenotfound. aspx"/>
<Error statuscode = "500" redirect = "js/error.htm"/>
</Customerrors>
<Authentication mode = "windows"/>
<Authorization>
<Allow users = "*"/>
</Authorization>
<Httpruntime maxrequestlength = "4000" usefullyqualifiedredirecturl = "true" executiontimeout = "45"/>
<Trace enabled = "false" requestlimit = "10" pageoutput = "false" tracemode = "sortbytime" localonly = "true"/>
<Sessionstate mode = "inproc" stateconnectionstring = "tcpip = 127.0.0.1: 43444" cookieless = "false" timeout = "20"/>
<Globalization requestencoding = "gb2312" responseencoding = "gb2312" fileencoding = "gb2312"/>
</System. web>
<Deleetask>
<Add key = "connstring" value = "uid = flash; password = 3.1415926; database = news; server = (local)"/>
</Appsettings>
</Configuration>
Here we will discuss how to set up database connections in web. config.
1. Connect to a database:
Add <configuration> in web. config
