My server prevent site scraping, but I need to allow my xml for scraping

First of all I already search the topic but it is different to what I need.

simplexml_load_file, cURL,file_get_contents allow_url_fopen already On.

Everything working fine.

My problem is my server is too much safe,it's ok for my content that can't easily graph by file_get_contents();

But now I have a project that need my other site (different server) to get content of my generated XML, I tried to find the ways to set .htaccess to allow just some folder to fetch with file_get_contents, simplexml_load_file

but it is not easy to find, and I already tried "allow from all" it doesn't work also.

I places all my xml in folder /share-content/ .htaccess already inside but not working.

Could someone help me about .htaccess in that directory to allow fetching content please.

Many thanks in advance.
