How to detect request headers stored in the library

[Evilglory1371]

Hello, I have a question. What should I do to detect known request headers stored in the database? How to operate it specifically, for example, when I retrieve a request header from the database, where should I put it for detection?

Hey, you could write a custom connector that reads information from the database and populates a Coraza transaction with all the data that you wish to analyze.
To give you an idea, you can take a look at tests like:

coraza/internal/corazawaf/transaction_test.go

Lines 199 to 213 in f1cfd13

	t.Run(name, func(t *testing.T) {
	waf := NewWAF()
	waf.RuleEngine = types.RuleEngineOn
	waf.RequestBodyAccess = true
	waf.RequestBodyLimit = int64(testCase.requestBodyLimit)
	waf.RequestBodyLimitAction = testCase.requestBodyLimitAction
	tx := waf.NewTransaction()
	tx.AddRequestHeader("content-type", "application/x-www-form-urlencoded")
	it := tx.ProcessRequestHeaders()
	if it != nil {
	t.Fatal("Unexpected interruption on headers")
	}

.
Here rules are added to the WAF instance, a transaction is created, and request headers are added and processed. Finally, it is checked if an interruption occurred.
