问题
I am using Elmah for logging in a ASP.NET MVC project and I am recieving lots of 404 errors for a path /prx2.php which in turn is passing a hash as a querystring param.
I assume this is a scanner trying to find vulnerabilities. Because I am not running PHP I am safe! However I would like to stop ELmah reporting this error.
Whats the best way to exclude these types of errors from being reporting without actually creating a /prx2.php page. I also would like to do this in a config file rather than doing it progmatically.
Any ideas?
回答1:
Elmah supports error filtering - Error Filtering link
This should solve the issue for you. You can either define your filter through code - in the Global.asx file, or within the xml config for elmah itself
回答2:
Step1: Configure config sections to include elmah errorFilter
section:
<configSections>
<sectionGroup name="elmah">
<!-- ... -->
<!-- this is the important part -->
<section name="errorFilter" requirePermission="false"
type="Elmah.ErrorFilterSectionHandler, Elmah"/>
</sectionGroup>
</configSections>
Step2: Configure the filter itself in <elmah>
section.
<elmah>
<!-- ... -->
<errorFilter>
<test>
<and>
<equal binding="HttpStatusCode" value="404" type="Int32" />
<!-- you may want to consider something more generic like pattern="/.+[.]php" -->
<regex binding="Context.Request.Url" pattern="/prx2.php" />
</and>
</test>
</errorFilter>
</elmah>
Step3: Include the Elmah.ErrorFilterModule
inside your application modules
Modern (IIS7+) version of including http module:
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<!-- ... -->
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"
preCondition="managedHandler" />
</modules>
</system.webServer>
Legacy (older IIS) version of including http module:
<system.web>
<httpModules>
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" />
</httpModules>
</system.web>
