Sorry, I can't parse that description.
- It's "temporary", not "temporal"
- There aren't Javascript fragments inside Blob objects
- I don't know what you mean by "give it to an inline WebWorker".

This URL is malformed, unless I've forgotten everything I know about 
HTTP URLs.
If you want an URL that accesses some protocol other than HTTP, please 
don't use HTTP URLs.

Unfortunately HTTP has the concept of an end-of-page (unless you use one 
of the infinite-document tricks that people have been using while 
waiting for webchannels to become available).

Please try to reformulate what you want to do rather than trying to 
express it in terms of HTTP; HTTP just doesn't work that way.
