Recently i added cache-control: no-transform to Firefox's ModifyHeader

reduce image quality/bandwidth) to EVERY page it serves me.
Other suggestions on the vodafone js insertion was to use
cache-control: no-cache and/or pragma: no-cache
These have nothing to do with insertions. They will simply cause a MISS
or revalidate on any cache along the way.
I chose to try no-transform in just cache-control as i thought it was
potentially less drama
After doing so im looking at my ratios and think that they may be
lower than before i added this directive via the addon.
Any gurus out there have an opinion on whether this affects caching or
not, to my understanding it shouldn't affect things, but just wanting
some clarification.
Thanks in advance,

That one does not affect caching.
If bms was altering the content in ways that broke caching your fix
could be causing the performance optimizations built into HTTP to start
working. Thats just a guess though.
