This section defines the appSetting parameters found in the web.config
These are settings that require a value in the appSettings section of the web.config file
Holds the version number of the currently installed version of Umbraco. This version number changes automatically when running the installer and the upgrade installer. It is not recommended to update this version manually as the upgrade installer might need to perform some actions to upgrade your site properly. The upgrade installer doesn't run when this version is the same as the version number in the Umbraco DLL.
A comma-separated list of files to be left alone by Umbraco. IIS will serve these files, and the Umbraco request pipeline will not be triggered.
<add key="umbracoReservedUrls" value="~/config/splashes/booting.aspx,~/install/default.aspx,~/config/splashes/noNodes.aspx,~/VSEnterpriseHelper.axd" />
A comma-separated list of all the folders in your directory to be left alone by Umbraco. If you have folders with custom files, add them to this setting to make sure Umbraco leaves them alone.
<add key="umbracoReservedPaths" value="~/umbraco,~/install/" />
The URL pointing to the Umbraco administration folder. If you rename the umbraco folder, you need to update this setting too.
<add key="umbracoPath" value="~/umbraco" />
If you are running multiple sites, you don't want the top level node in your URL. Possible options are true and false.
<add key="umbracoHideTopLevelNodeFromPath" value="true" />
Strips .aspx from URLs on the frontend when set to true.
This setting is only important to older IIS configurations where extension-less URLs weren't supported very well.
Configures the number of minutes without any requests being made before the Umbraco user will be required to re-login. Any backoffice request will reset the clock. Default setting is 20 minutes.
<add key="umbracoTimeOutInMinutes" value="20" />
The default language to use in the backoffice if a user isn't explicitly assigned one. The default is English (en).
Makes sure that all of the requests in the backoffice are called over HTTPS instead of HTTP when set to true.
By adding this to appSettings you can specify a new/different folder for storing your css-files and still be able to edit them within Umbraco. Default folder is ~/css.
By adding this to appSettings you can specify a new/different folder for storing your media files. Default folder is ~/media.
By adding this to appSettings you can specify a new/different folder for storing your Javascript files and still be able to edit them within Umbraco. Default folder is ~/scripts.
By adding this settings to the web.config you will be able to send out emails from your Umbraco installation. This could be notifications emails if you are using content workflow, or you are using Umbraco Forms you also need to specifiy SMTP settings to be able use the email workflows. The forgot password function from the backoffice also needs a SMTP server to send the email with the reset link.
<system.net>
<mailSettings>
<smtp from="[email protected]">
<network host="127.0.0.1" userName="username" password="password" />
</smtp>
</mailSettings>
</system.net>
These are settings that have default values but can be overridden by creating the appSetting and setting its value in the web.config
The default value is: ~/App_Data/umbraco.config
The value must be set to a virtual path with a prefixed tilde (~)
The default value is: false
Generally set to false but when set to true the content XML file (normally stored in ~/App_Data/umbraco.config) will be stored in the local servers' Temp (CodeGen) folder. This is handy for load balanced environments when the website is running from a central SAN based file system (non-replicated).
If you are not running a load balanced environment on a central SAN based file system (or similar) ensure that this setting remains set to false.
The default value is: Default
This setting replaced the umbracoContentXMLUseLocalTemp setting.
This setting controls where Umbraco stores the XML cache file.
The options are:
Default- Umbraco cache file will be stored inApp_Dataand theDistCacheandPluginCachefolders will be stored in theApp_Data/TEMPfolderEnvironmentTemp- All files will be stored in the environment temporary folderAspNetTemp- All Files will be stored in the ASP.NET temporary folder
The default value is: Default
This setting replaced the umbracoContentXMLStorage setting.
This setting controls where Umbraco stores the XML cache file, the DistCache and PluginCache TEMP folders. Version 1.9.6+ of ClientDependency Framework also observe this setting.
The options are:
Default- Umbraco cache file will be stored inApp_Dataand theDistCacheandPluginCachefolders will be stored in theApp_Data/TEMPfolderEnvironmentTemp- All files will be stored in the environment temporary folderAspNetTemp- All Files will be stored in the ASP.NET temporary folder
The default value is: 7
When this value is set above 0, the backoffice will check for a new version of Umbraco every 'x' number of days where 'x' is the value defined for this setting. Set this value to 0 to never check for a new version.
The default value is: false
This is not a setting that commonly needs to be configured.
This value is primarily used on Umbraco Cloud for a small startup performance optimization. When this is true, the website instance will automatically be configured to not support load balancing and the website instance will be configured to be the 'master' server for scheduling so no master election occurs. This will save 1 database call during startup.
