[SR-Users] routing SIP REGISTER with app_perl

[Vik Killa]

Thanks Daniel,
I want to remove the htable entry after the register goes through, and I
also want to check if the htable entry exists later.

I see

sht_rm_value_re("ha=>.*");

to remove the htable entry but how do i later check if the key exists?

Thanks
/V
