I've setup a website for IIS compression, but it doesn't appear to be working for HTTPS, just HTTP. Is there something that needs to be configured to get this to work, or does this not work in IIS? What options are there?
UPDATE: According to this the compression is occurring before the encryption. If compression is occurring for SSL requests, where do I see it?
UPDATE2: I went back to the metabase.xml file and discovered that the changes I made were gone. Here's what I had:
HcDynamicCompressionLevel="9"
HcFileExtensions="htm
html
js
css
txt"
HcOnDemandCompLevel="10"
HcPriority="1"
HcScriptFileExtensions="asp
dll
aspx
exe"
I'm wondering if the in-memory metabase overwrote the changes I made before I was able to run IISRESET /RESTART??
Thanks!

I'm not exactly sure how IIS works but I believe that compression gets applied at the end. If that is the case, then it won't work well with encrypted data, which has random-like characteristics. However, it may still be possible to compress your data manually in your application before handing it off to IIS.
The compression should work fine with both normal and ssl traffic, setting it up in IIS can be somewhat tricky, it's often not enough to just toggle the checkbox since it will only compress certain filetypes per default.
IIS Compression
Is your SSL site is pointing to the same application in IIS ? Are you using anything like an SSL accelerator hardware with your server ?
First try the form to the right on the port80 site to see if IIS is compressing: http://www.port80software.com/

I wrote a classic ASP script (.asp) for a customer a while back. it was running on IIS v6.1 Windows 2003. The customer contacted me and said they had a catastrophic server failure and restored from backup but my script isn't running now. I logged onto their server to check it out and IIS is serving the file (I am prompted to save when I browse to the script) but not executing the script.
Several people's hands were in the server before they called me, I think this is probably a simple config setting someone tried before they figured out how to enable the "ASP" web server roll feature. But for the life of me I can't figure out how they did it. this is obviously not the default behavior. If I was trying to get this behavior I would add the .asp extension to the MIME types, but I checked and it isn't there.
What could cause IIS to serve the source of the ASP script without executing it?
Based on your question I am assuming your restored server is also windows server 2003 ... in that case you will go to the file\folder and the permissions and select execute permission to enable a server side script processor to handle that request. Been almost a decade that I have touched a 2003 server so I can’t give you the exact steps ... but, you want to enable script permissions on that folder(I think, don’t remember if it’s granular enough to drill down to a file). Also, why on earth are they still running server 2003? Is that version even supported yet?
If it’s IIS 7, you want to make sure your app pool is in Classic ASP mode first off. Then go to site and then the handler mapping section, click edit and configure it that way.
This post needs help from experienced iis administrators, but must be explained in details for EXTREME newbies.
What I am doing:
I have two computers, both running Windows 10. One is a desktop and one is a laptop.
iis is enabled on both computers. Each computer can access the iis web server from the other and pull up a page from the other - using the ip address.
There is no DNS or host files being used (this is by ip address only), nor do I want to use any sort of naming.
Both computers are running an identical website, and the website files are in a different directory than the default. The structure is like this:
C:\inetpub\ROOT\myWebsite\myIndex.html
web.config
Changes I've made - now a few problems.
On both computers I have deleted the DefaultAppPool and the default website that comes installed with iis. This has not stopped the website from completely working, so adding that back seems unlikely to fix my problem.
I have deleted my application pool and website from iis (never deleting the actual files from the file system) several times, and added it several times. Each time I do this, my site comes back, but with the same problem I am having.
I have deleted all of the default documents, and the only default document listed in iis is myIndex.html.
myIndex.html initially displays a graphic image (using the standard tag), and this image comes up. Sort of. See explanation below.
The problem I am having
Before I started this project, I had iis working on the desktop with the default site and app pool and simply added some of my own files with really simple text content and some pics. I had replaced the default iis splash image with my own image, and all that worked with no problem.
the image that comes up is a link to another page that has a list of links to other stuff in my website. It all works no problem there.
Now, with the setup I have now, on the desktop I was originally using (in the paragraph above) if I pull up my website locally, myIndex.html loads in the browser and my image comes up, and everything works fine.
The same is true on the laptop, when I access the site locally.
However, if I attempt to access the desktop site (using its ip address) from the laptop, it pulls up the old splash image from the default site I deleted.( I left those files there even though I deleted the site from within iis). All those files are in the default location C:\inetpub\wwwroot.
If I move those files to another directory, thus leaving C:\inetpub\wwwroot completely empty, then when I access the site on the desktop (via the ip address) from the laptop, my new site comes up without a problem.
While it seems I may have solved my problem by moving the file from the previous project, doing that does not teach me how iis is actually working, and why files from a website that no longer exists in iis are still being accessed from remote computers.
So, please teach me something about the internal workings of iis, and how it chooses to access the different application pools and websites.
Again, please word your answers for complete newbies, because I know a little but not enough to get real technical.
I have been reading posts on stackexchange.com and other sites; links to microsoft docs etc. That's not helping as those docs are expecting too much prerequisite knowledge, and speaking in terms that are not really explaining things in a way I can understand.
You have described several different problems. I will try to address each of them (contrary to S/O recommendations).
First, when you make changes, and they don't seem to show up, it is usually because of caching. IIS always wants to cache files/configs. So does your web browser. So, to force an accurate test, you need to dump your browser cache and cycle IIS (to make sure it drops its cache and loads new files and configs). Start there.
Second, IIS is designed for settings inheritance. Which means, each app and each folder will inherit settings and permissions from the parent, unless you override them. Overriding them can be done by files and/or IIS configs (application vs folder). The IIS configs are the stronger of the two.
Also, the IIS config for "default files" might have come into-play for your test. If you didn't set up MyIndex.html as the top-most default file, then IIS would look for other files first. In fact, if you don't have MyIndex.html in the list of default files, IIS would have to depend on your app to choose that as a default page (MVC routing, etc).
I have several sites running in IIS Express for the same project.
They are mapped to real domains via the host file, local.xxx.com etc. instead of localhost:XXX
I add a binding for https, under one site in the applicationhost.config file , but it is constantly removed, seemingly randomly by VS2012. Meaning, I add it. save it, and it works, then at some point in time later, VS2012 edits my applicationhost.config file and removes, just the https binding, leaving the http binding intact. It doesn't do this on all sites in the config, even if those sites are in the same solution. Just one site.
How do I make it stop?
i have a problem where my ASP.NET web application files (.js, .css, .aspx) doesn't get compress when i access it from https. However the files get compressed when i accessed it from http. Any idea what causing this problem?. It over a week and i cannot find any solution from the net. I have ask my network administrator to check proxy settings but they said all ok. My last resort to reinstall IIS but i need to know if you guys have any better solution.
For some magical reason ii6 started to cache pages on the server. Even if I remove the page, it is still displayed. I tried to follow couple suggestions but no luck.
That's what I did so far:
Deleted \WINDOWS\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files
Unchecked 'cache ISAPI extensions' in the IIS configuration.
Added 'Cache-Control no-cache' to HTTP headers in properties.
Tried to create the page that clear the cache http://www.dotnet247.com/247reference/msgs/13/67641.aspx
Update: also tried to disable asp cache
IIS ASP Caching
But the files in v2.0.50727\Temporary ASP.NET Files are still created
If anybody has other suggestions, please share.
Thanks.
Please give the delete permission for IIS user on below folder. these files will be deleted automatically by IIS
For 64 bit OS folder path:
\WINDOWS\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files
My classic ASP pages WOULD NOT refresh from any browser. Finally, stopping and starting the IIS service (IIS6) fixed the problem.
You, too, can go bonkers, just like me. Simply have IIS start giving out stale pages! A bargain at half the price!
Did you try restarting the IIS server to see if that stops it from displaying? If it doesn't, then it might not be a caching issue.
I believe restarting the server is supposed to clear the cache.
Maybe the problem isn't the IIS, but a web proxy between your browser and your web server caching the page?
Or a wrong DNS settings pointing to another server which holds a copy of that web/page? You could also look on the same IIS if there is another web configured and host headers got mixed up, making you test on the wrong web.
I might just say the obvious here but have you tried recycling the application pool?
Thanks for replies guys.
I figured out that it wasn't the caching issue. I didn't cleared out Bin folder and the compiled version of the page with extension .compiled was seating there all the time. I don't what changed this time, but I followed the same process like 100 times before and copied files on top without clearing Bin.
I should be more accurate with such things.
