Bash - Source a file with "/"

Question

I have a cache in the filesystem which I implemented this way.

To store a value I do something like

echo ""$KEY1"_"$KEY2"="$VALUE" >> $CACHE_DIR/$INDEX.cache

To get a value, first I source the cache file:
```
source $CACHE_DIR/$INDEX.cache
```
and then I echo the "$KEY1"_"$KEY2"

Cache example:

foo1_foo2=wohohhowwho

The problem with this, is that I have some keys that have a "/" in it, so when I have this:

foo3_foo/4=wohohhowwho

and source the file, it says

cache/15637.cache: line 1: foo3_foo/4=wohohhowwho: No such file or directory

because of the /.

Is there an option to the source command to not search in the path for files and only take in count the content as vars? I could escape the /, but is there another way?

You seem to be confusing bash scripts with a storage mechanism... — Ignacio Vazquez-Abrams

I'm not confusing anything, I use a cache that works fine for me. I only have one case with problems. Thanks anyway — Federico Lenzi

There is no other way since / is not allowed as a character in bash variables.

you have to ``sanitize'' you key as bash only support for variable name: letter, digit and the underline character.

KEY1=${KEY1//\//_}
KEY2=${KEY2//\//_}
