> When the tika "detects" the following file, it returns the wrong content type:
> {{$ curl -I [https://wiki.charltonslaw.com/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.min.js]}}
> {{HTTP/1.1 200 OK}}
> {{Server: nginx/1.10.3 (Ubuntu)}}
> {{Date: Fri, 16 Mar 2018 10:09:54 GMT}}
> {{Content-Type: text/x-matlab}}
> {{ [snip]}}
> {{X-Frame-Options: SAMEORIGIN}}
> However, the unminified version of the same file returns the correct type:
> {{$ curl -I [https://wiki.charltonslaw.com/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.js]}}
> {{HTTP/1.1 200 OK}}
> {{Server: nginx/1.10.3 (Ubuntu)}}
> {{Date: Fri, 16 Mar 2018 10:10:25 GMT}}
> {{Content-Type: application/javascript}}
> {{ [snip]}}
> {{X-Frame-Options: SAMEORIGIN}}
> The problem this causes is when my xwiki installation is behind an ssl proxy (nginx) and I enable the add_header X-Content-Type-Options nosniff; header.
> Modern browsers return the following error:
> {quote}Refused to execute script from '[https://wiki.charltonslaw.com/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.min.js|https://wiki.proxy.domain/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.min.js]' because its MIME type ('text/x-matlab') is not executable, and strict MIME type checking is enabled.
> {quote}
> My "solution" is to disable the strict mime type checking in the ssl proxy, but I don't think that is idea. It'd be better of the matlab parser didn't claim random minified js files as its own.
>
> Note:
> Edit: I marked the problem as being with the matlab parser, but that may be incorrect - I'm not sure exactly what code actually does the detection.
