I have a website deployed on Azure Websites and I want to disable pool recycling.
If you have a regular IIS installation, you can disable this in application pool advanced settings by setting "Recycling -> Disable overlapped recycle" to true.
Yet I can't seem to find this option in the azure management console, nor do I find any information on this subject online.
Any pointers would be greatly appreciated!
Thanks a lot Puneet Gupta for pointing me in the right direction!
I couldn't use the exact solution, but it set me on the right path.
Here's how I solved this:
1) Get your hands on the applicationHost.config.
The easiest way is going through the SCM Console via "files" and then follow the links in json.
In the end, you end up here: https://YOUR_WEBSITE_NAME.scm.azurewebsites.net/api/vfs/LocalSiteRoot/Config/applicationhost.config
2) Identify the current status of overlapped recycle.
In the applicationHost.config file, look for the "applicationPools" element
It should look like this:
<applicationPools>
<add name="YOUR_SITE_NAME" managedRuntimeVersion="v4.0">
<processModel identityType="ApplicationPoolIdentity" />
</add>
<add name="~1YOUR_SITE_NAME" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated">
<processModel identityType="ApplicationPoolIdentity" />
</add>
</applicationPools>
If you see this, then overlapped recycle is ENABLED!
You can't write directly to this file but fortunately microsoft gives us the power to transform it!
3) Transform it!
You can transform the applicationHost.config file by placing an applicationHost.xdt file in the /site directory of your website (mind you that the website itself is deployed in the /site/wwwroot directory, so your applicationHost.xdt transform must reside in the parent folder of where your website is.
If you want to disable overlapped recycle, then this is what you put in the file:
<?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">>
<system.applicationHost>
<applicationPools>
<add name="YOUR_SITE_NAME" xdt:Locator="Match(name)">
<recycling disallowOverlappingRotation="true" xdt:Transform="Insert" />
</add>
<add name="~1YOUR_SITE_NAMEd" xdt:Locator="Match(name)">
<recycling disallowOverlappingRotation="true" xdt:Transform="Insert" />
</add>
</applicationPools>
</system.applicationHost>
</configuration>
4) restart the site
finally you need to restart your site to have your transformations applied.
After restart, go to step 1 again and you should now see this instead:
<applicationPools>
<add name="YOUR_SITE_NAME" managedRuntimeVersion="v4.0">
<processModel identityType="ApplicationPoolIdentity" />
<recycling disallowOverlappingRotation="true" />
</add>
<add name="~1YOUR_SITE_NAME" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated">
<processModel identityType="ApplicationPoolIdentity" />
<recycling disallowOverlappingRotation="true" />
</add>
</applicationPools>
et voila: overlapped recycle is now disabled on your azure website.
You will have to use a XDT transform similar to the one mentioned in https://github.com/projectkudu/kudu/wiki/Xdt-transform-samples#remove-all-your-recycling-options-from-your-net-4-application-pool-and-make-it-available-always.

We are using the request filtering for file extensions in our web.config like so:
<fileExtensions allowUnlisted="false">
<add fileExtension="." allowed="true" />
<add fileExtension=".aspx" allowed="true" />
<add fileExtension=".ashx" allowed="true" />
<add fileExtension=".asmx" allowed="true" />
<add fileExtension=".axd" allowed="true" />
<add fileExtension=".html" allowed="true" />
<add fileExtension=".htm" allowed="true" />
However we have run into a problem. When we go to a url with a directory with a dot in it, for example "https://localhost/myamazing.folder" it will return a "HTTP Error 404.7 - Not Found" since it now thinks that its an extension that's not allowed.
When allowUnlisted is set to true, or without any filtering, iis will perform a courtesy redirect because its a folder. Is there anyway to keep this redirect behavior intact while still filtering extensions?
This is iis default security setting if you want to allow the unspecified extension you need to enable it by using
another way is set allow file name extension and then set allow URL by following below step:
In the "URL" tab allow the list of URLs->add the URL which you only want to allow.
that's how it will redirect URL /myamazing.folder to /myamazing.folder/
if you are using asp.net mvc site you can refer to below link:
Dots in URL causes 404 with ASP.NET mvc and IIS
Our website uses both dynamic and static compression. I know that compression can be enabled/disabled on a web.config level, but that the mime-types for static and dynamic compression cannot be enabled at a web-config level.
Meaning, this section:
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" staticCompressionIgnoreHitFrequency="true">
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
<staticTypes>
Stuff
</staticTypes>
<dynamicTypes>
Stuff
</dynamicTypes>
</httpCompression>
Must go in the applicationHost.config, and is generally edited using appcmd.exe.
I know there is a location element in the applicationHost.config that allows setting many things on a per website basis, but I can't seem to find anywhere if mimetypes for dynamic compression are one of them.
I have tried overriding these settings using a location element, but have not had any success and cannot find documentation stating it's possible for the httpCompression element.
To make matters worse, we install our product as a web application under the default site, so really we want to enable these dynamic compression mime-types only under our application, instead of site (or server) wide. Is this possible?
Generally, we are using IIS 7 and above. Right now our minimum is 7, so assume anything needs to work with that.
My question is:
Can httpCompression settings be set in the applicationHost.config per website and possible per web application under a web site?
Is there a different way to enable dynamicCompression specifics on a website/web application level?
Just an important precision: There is one prerequisite to ensure that you can add MIME Types in the "web.config" file:
It is possible to add MIME Types in the <staticTypes> and <dynamicTypes> sections at the website level (in "web.config") only if this is explicitely allowed at the "applicationHost.config" level, as explained in this solution from Stack Overflow:
The important thing to note is that modifying your
applicationHost.config (in %windir%\system32\inetsrv\config) from the following setting:
<section name="httpCompression" allowDefinition="AppHostOnly" overrideModeDefault="Deny" />
to:
<section name="httpCompression" overrideModeDefault="Allow" />
will enable configuration of the httpCompression tag under the
system.webServer tag in your web.config.
Yes you can very well add dynamic and static types in web application's web.config file. ApplicationHost.config will define global compression settings and if you want to override them in your application you can do so. Following is sample from one of my application.
<system.webServer>
<modules>
<remove name="FormsAuthentication" />
<add name="Glimpse" type="Glimpse.AspNet.HttpModule, Glimpse.AspNet" preCondition="integratedMode" />
<remove name="UrlRoutingModule-4.0" />
<add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" />
</modules>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<add name="Glimpse" path="glimpse.axd" verb="GET" type="Glimpse.AspNet.HttpHandler, Glimpse.AspNet" preCondition="integratedMode" />
</handlers>
<httpCompression>
<dynamicTypes>
<remove mimeType="text/*" />
<add mimeType="application/json" enabled="true" />
</dynamicTypes>
</httpCompression>
Here remove tag in dynamicTypes removes global entry coming from ApplicationHost.config
add tag is adding additional mimeType on top of global entries from applicationHost.config. This addition will be applicable only for whose web.config is being modified.
Similarly you can modify staticTypes as well.
I'm trying to get a custom image handler for .gif files working in an MVC website on my development machine which runs Visual Studio 2013. I'm basing it on an article by Scott Hanselman in which he dynamically generates a png.
I have a class which inherits from IHttpHandler and implements a ProcessRequest method (I don't think the code is relevant so I'm not including it). I've added an entry to the web.config like this:
<system.webServer>
<handlers>
<add name="ImageHandler" verb="*" path="*.gif" type="StaticContentWorkbench.Infrastructure.CustomGIFHandler" />
Unfortunately this isn't working so I did some research and found out that I probably need to alter the IIS configuration so that .gif files are handled by ASP.NET. I tried adding an entry to the system.webserver - handlers section of the IISExpress application.config file just before the last entry:
<add name="PageHandlerFactory-ISAPI-4.0_64bit_Add_Gifs" path="*.gif" verb="*" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
<add name="StaticFile" path="*" verb="*" modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" resourceType="Either" requireAccess="Read" />
However this hasn't worked either and now I'm pretty much stuck.
How do I correctly configure IISExpress 8 to use ASP.NET to handle requests for a .gif file?
I had the same problem,
what worked for me was this
<system.webServer>
<handlers>
<add verb="GET,HEAD" name="DocHandler"
path="*.pdf"
type="Web.DocHandler" />
</handlers>
</system.webServer>
Problem is that you need to map every extension singularly, you cannot put multiple extension in the path property.
In your case, try to specify the verbs you need instead of *
Hope this helps

I'm adding that in appliationHost config of IIS to solve localDb problem in IIS what I see in this article

Can you guys help me to avoid this error?
Unrecognized attribute 'setProfileEnvironment'
It looks like you are attempting to place the value inside of an actual application pool. That attribute lives outside of a defined application pool, and lives in appicationpooldefaults.
<applicationPoolDefaults>
<processModel identityType="ApplicationPoolIdentity" loadUserProfile="true" setProfileEnvironment="true" />
<applicationPoolDefaults>
Quick search for the error you provided points to outdated or broken IIS (the assembly that implements setProfileEnvironment attribute, or one of its dependencies, is either missing or broken). At least that's best guess based on the data provided.
How can I enable logging of any exceptions that occur in my handlers, or codecs etc. in IIS?
When googling for that, I found a couple of different ways on how to setup tracing. One of those actually worked, but the trace file (xml) is not very user-friendly. I'd like to have something like a standard text log file that I can view and manipulate using standard tools.
OpenRasta uses TraceSources to log requests, so you can use any implementation of log files for tracesources by providing the right configuration in your web.config.
<system.diagnostics>
<sources>
<source name="openrasta" switchName="OpenRasta">
<listeners>
<add name="ErrorLog" />
</listeners>
</source>
</sources>
<switches>
<!--<add name="OpenRasta" value="Warning,Error"/>-->
<add name="OpenRasta" value="All"/>
</switches>
<sharedListeners>
<add name="ErrorLog"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="c:\myListener.log" />
</sharedListeners>
</system.diagnostics>
I'm not sure however what you mean by standard text log files. Standard log files use standard logs that IIS generates itself already, this part of your logging does not change and is configured the usual way in IIS.
