what was the question? you’ve mentioned that there was a post about it, but not asked a question?

I remember reading somewhere if the system detects that your .htaccess file is trying to cercumvent the security system, it will be automatically deleted

The post was that the .htaccess gets deleted as soon as it is uploaded. No goofy or unusual stuff in it. Just a simple http to https redirect. That’s standard and not violating anything. It used to work in the past. Not hiding anything, no ill intent.

It looks like this uses a Rewrite condition that touches `i`. I tried this,

> Website URL [For security reasons, the link will not be disclosed.] Error Message .htaccess file keeps being removed. Other Information I am installing an .htaccess file that is responsible for both HTTPS redirect, and to remove ?i=1 from the link. The file is 500B, which is 0.5KB, loads (way) under the posted limit here: [Why are my files deleted after uploading them](https://forum.infinityfree.com/t/why-are-my-files-deleted-after-uploading-them/49310/1) The .htaccess code is this: play_button Cool Code Problem is, after I save the file and upload it to the server, it is removed without …

But the file is removed.

Do note that InfinityFree is powered by [iFastNet](https://www.infinityfree.com/go/ifastnet), which has the rights to remove files that they deem are harmful or too large. Seemingly, when touching the `i` variable, this is a harmful thing.
