[MS4W-Users] Hosting Map Cache in IIS

[Georgios (Smartsoft)]

Hi

Some background. We have a website hosted in IIS. We installed Map Server For Windows using Apache on another port number (:80 was taken by IIS). However, when we tried to do anything with the canvas image such as save to a PNG, or print in a PDF, it would give an error in the JavaScript console "tainted canvases may not be exported". We managed to solve this for Map Server by following the instructions for IIS and FastCGI, hosting Map Server as an application sub directory, which works perfectly.

However, when we try and run Map Cache through the browser, it gives a 500 error below.

HTTP Error 500.0 - Internal Server Error
C:\ms4w\Apache\cgi-bin\mapcache.fcgi.exe - The FastCGI process exited unexpectedly

We've set up the Environment Variable to point to the XML file, as well as set up the web.config (see below). I feel like I'm missing a configuration to get Map Cache working. There's plenty of instructions for Map Server, but I couldn't find anything specifically for Map Cache online. If there's a simple solution it may be worth updating the instruction manual. Any help would be appreciated. I've attached some relevant information below, as well as a screenshot of the environment variables and the website structure.

Map Server web.config (working)
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
                <system.webServer>
                                <handlers>
                                                <add name="MapServerFastCgi" path="*" verb="*" type="" modules="FastCgiModule" scriptProcessor="C:\ms4w\Apache\cgi-bin\mapserv.exe" resourceType="Unspecified" requireAccess="Script" allowPathInfo="false" preCondition="" />
                                </handlers>
                                <caching enabled="true" enableKernelCache="true" />
                </system.webServer>
</configuration>

Map Cache web.config (not working)
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
                <system.webServer>
                                <handlers>
                                                <add name="MapServerFastCgi" path="*" verb="*" type="" modules="FastCgiModule" scriptProcessor="C:\ms4w\Apache\cgi-bin\mapcache.fcgi.exe" resourceType="Unspecified" requireAccess="Script" allowPathInfo="false" preCondition="" />
                                </handlers>
                                <caching enabled="true" enableKernelCache="true" />
                </system.webServer>
</configuration>

Kind regards
