How prevent third party applications such as Internet Download Manager downloads pre-gziped files?-CodePudding

This

I'm using Url rewriter to load pre-gzip files on server instead of original js files on web.config:

<rewrite> <outboundRules rewriteBeforeCache="true"> <rule name="Custom gzip file header"> <match serverVariable="RESPONSE_CONTENT_ENCODING" pattern=".*" /> <conditions> <add input="{REQUEST_URI}" pattern="\.gz$" /> </conditions> <action type="Rewrite" value="gzip"/> </rule> </outboundRules> <rules> <rule name="Rewrite gzip file"> <match url="(.*)"/> <conditions> <add input="{HTTP_ACCEPT_ENCODING}" pattern="gzip" /> <add input="{REQUEST_FILENAME}.gz" matchType="IsFile" /> </conditions> <action type="Rewrite" url="{R:1}.gz" /> </rule> </rules> </rewrite>

In addition I've installed

How can I not let a third party application such as Internet Download Manager, stay between the response which is sent from the server and client which want to received it and gzip files works properly?

CodePudding user response：

The following steps could help:

in the Internet Download Manager, open the options;

select file types;

you can either edit the file type (e.g. GZ, GZIP) or edit the sites list that don’t start downloading automatically

CodePudding user response：

I think you are making a wrong request, you should make a request to vendor.js, and not vendor.js.gz (probably in your HTML). I never worked with IIS but the server should be configured in a way that if it gets the request header Accept-Encoding: gzip then it passes the gzipped file with the response header of Content-Type: gzip.

For example, if you look at StackOverflow requests, it gets some .js files with the response header of Content-Type: gzip. This tells the browser that the content should be uncompressed first.

As you can see in the images, it's only a request to a .js file.
