Rewrite rule enhencement

[yjwu-leadstec]

I found a small mistake from dispatcher/src/conf.d/rewrites/rewrite.rules line 31. I guess you intended to match ".html, .svg, .png", but because of the lack of an back escape, the rule also matched "ahtml, bsvg, cpng". It should add an escape character before the ".".

Expected Behaviour

match ".html, .svg, .png"

Actual Behaviour

also matched "ahtml, bsvg, cpng"
