I have set up my IIS (v 10.0.14393.0) with rules for a specific path to distribute a MJPEG stream I have locally on port 8081.
In a web page I have included a link to the specified path, <img src="/videoproxy/streamproxy/mjpegvideo.jpg'"></img>
It all works, but after loaded for a while the w3wp.exe process dies. (When looking in task manager I can see the memory used grows...)
I think this is because IIS caches all the images, but I am not sure.
I have asked this question before on the forums and only was adviced to do log of the problem. However reading and understanding the log did not do anything for me.

According to your description, it is impossible to reproduce your problem.
Without error messages and logs, it is impossible to find out where the problem is.

Memory issue for reverse proxy for MJPEG stream

Hi Sam!
I can give you information of setup so you can see for your self. (In this case with an external mjpeg stream of a camera outside here in Uppsala.)
I hope this is a configuration issue. I think that mjpeg get cached...
Have a log from earlier somewhere, will try find that to post to you.
Web structure:
webroot/
webroot/testfolder/videos/
webroot/testfolder/index.html
webroot/testfolder/web.config
web.config:
<?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="Reverse Proxy To videostream" enabled="true" stopProcessing="true"> <match url="^videos/(.*)" /> <action type="Rewrite" url="http://2.248.130.108:81/mjpg/video.mjpg" /> </rule> </rules> <outboundRules> <rule name="Reverse Proxy Outboundrule to videostream" preCondition="ResponseIsHtml1" enabled="true"> <match filterByTags="A, Area, Base, Form, Frame, Head, Img, Link" pattern="^http://2.248.130.108:81/mjpg/video.mjpg" /> <action type="Rewrite" value="/testfolder/videos/test.jpg" /> </rule> <preConditions> <preCondition name="ResponseIsHtml1"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^(.*)" /> </preCondition> </preConditions> </outboundRules> </rewrite> </system.webServer> </configuration>

Sam.
I have found the debug-log I made late last year of this issue.
What part of debugdiag analysis report is interesting for you?
I have 2 warnings
