Table 1
After getting the configuration data of application system configuration item, come more using the configuration data obtaining
New caching.In the present embodiment, the concrete form of caching is Hash table, can improve inquiry using Hash table
Speed.The present embodiment updates caching with the configuration data getting, and concrete grammar is as follows:
Through Hash calculation, corresponding cryptographic Hash is obtained to each domain suffix；
By cryptographic Hash and Hash table array length phase with obtain corresponding Hash table array position；
According to this Hash table array position, this domain suffix is put in Hash table.
If it should be noted that cryptographic Hash is identical, domain suffix content differs, then with chained list
Form order arranges.After the completion of all domain suffix are all added, obtain data knot as shown in Figure 2
Structure schematic diagram, wherein .ac.cn and .jl.cn order arrangement in the form of chained list .farm and .name .pay
In the form of chained list, order arranges.
Simultaneously for the domain suffix rank in table 1, after taking the maximum domain name in above-mentioned domain suffix
Sew rank to be stored separately in caching.Because commonly using most 2 grades of domain suffix, therefore this enforcement at present
In example, regulation acquiescence domain suffix rank is 2.If after the domain name of configuration data in future data base
Sew rank and be more than 2, then, when updating caching, update this maximum domain suffix rank in caching simultaneously.

Character string, such as url.In nslookup suffix, according to domain suffix rank, create canonical
Expression formula, searches the part with matching regular expressions in the domain name of input by the method for recurrence,
Judge whether do not exist in caching, domain suffix rank is successively decreased and obtained again, until obtaining domain
Name suffix or current suffix rank are equal to 0.
It is exemplified below:
In inquiry, if the query argument of input is not domain name, but url, for example:
http://www.alibaba-inc.com；Then need according to by regular expression
"(http://|https://)？([^:/]+)(/|:)*？" tentatively filtered, matched the domain name needing to be inquired about
Part.
The url of such as input is: http://www.alibaba-inc.com；Then match:
www.alibaba-inc.com.
If input inquiry parameter is directly domain name, for example: www.alibaba-inc.com, then directly use
It is as the domain name needing inquiry.Then domain suffix rank, this domain suffix level are obtained from caching
The domain suffix rank reading from caching, i.e. the maximum level of current domain suffix, and cache
In domain suffix rank be 2.
Then according to the domain suffix rank (assumption value is n) obtaining from caching, just splicing n time
Then expression formula, shape such as (. { 1 } [^.]+"), round bracket interior section repeats n time, using the side of recurrence
Method is inquired about.I.e. according to n, splice regular expression, then mated with the domain name of input,
Judged after coupling judge the result matching whether in the buffer, if cache hit,
Return matching result；If in the buffer, not making n=n-1, regenerate regular expression,
Execute above-mentioned query steps again, until there being return value, or n is equal to 0, returns null.
For example as n=2, the regular expression of splicing is: (. { 1 } [^.]+. { 1 } [^.]+)；
Match: .alibaba-inc.com it is clear that this result not in the buffer；
Then make n=2-1=1, the regular expression of splicing is: (. { 1 } [^.]+)
Mated again, acquired domain suffix: .com, cache hit, return last knot
Really: .com.
