To enable generation of a trace file for Identity Server 3, insert the following in web.config file. If <system.diagnostics> is not already present in the file, insert the section between the sections <appSettings> and <system.web>. To disable the trace later, it'll suffice to comment out the <add> element.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
<system.diagnostics>
<trace autoflush="true" indentsize="4">
<listeners>
<add name="trace.-log" type="System.Diagnostics.TextWriterTraceListener" initializeData="Trace.log" />
</listeners>
</trace>
</system.diagnostics> |
The initializeData attribute in the <add> element points to the trace file. When no path is specified, the file is created in the web site folder which may be inappropriate and can be a security risk.
Consider a better place and be aware that the application pool identity must have write access to the folder (which, in fact, it may not have to the web site folder).
